Ooops!
|
|
======
|
|
In my review of FoReM-XE Professional in issue 203, I mentioned that the
|
|
hardware and software of the Final Frontier in Philadelphia, PA had been
|
|
sold and was no longer up and running. Well, sorta, I think, maybe?
|
|
Um, I heard on my networked message base that such was not the case! I
|
|
called this past weekend, and sure enough, it was up!? It is not at
|
|
present in the network though. Am checking into it further.
|
|
|
|
Shareware
|
|
=========
|
|
Have a real jewel of a program to tell you about. I have been using
|
|
Read.com ever since I put up my BBS. I never thought that anything
|
|
would replace it as my 'quick take a look at the docs' program. Well,
|
|
much as in life, I have found something that has replaced it!
|
|
|
|
VTEX
|
|
----
|
|
When I first spotted VTEX, I thought it was another 'Vidtex' program.
|
|
Then I saw that it was a 'text viewer'. -Hmm, can't IMAGINE anything
|
|
as good as READ.COM!- sez I. WRONGO! Boy and how! It was the next day
|
|
before I got around to looking over the Docs for it.
|
|
|
|
Once I saw the Docs, I hurried up and tried it out! Naturally, I had
|
|
to reload the docs several times to see how to try all the features!
|
|
(who reads docs all the way through the first time? <Grin>)
|
|
|
|
This is one *many featured* program! You can search for a string,
|
|
scroll up or down one page(or 10 pages!), not show leading spaces, read
|
|
either Atascii or Ascii.
|
|
|
|
Here are the docs for it:
|
|
|
|
VTEX - The Text Viewing Utility Version 1.0 8/4/91
|
|
|
|
Program and Documentation by: Larry Richardson, P.O. Box 472, Aurora,
|
|
Co. 80010
|
|
|
|
This program is distributed as SHAREWARE. I have spent a great deal of
|
|
time designing, coding, debugging, and modifying this program. Any
|
|
donations I receive for my time and effort will encourage me to continue
|
|
supporting this program, as well as writing new software for the Atari
|
|
8-bit computer. Thank you.
|
|
|
|
I. What does it do?
|
|
|
|
VTEX is a utility that allows you to view any file on the screen. If
|
|
you have used DOS to view a file (copy from the file to E:), you already
|
|
know how unfriendly it is. VTEX is an attempt to give the Atari 8-bit
|
|
users an easier and more powerful method to view a file.
|
|
|
|
II. Features
|
|
|
|
VTEX can page through a file, both forward and backward. It has the
|
|
ability to skip to the last page and back to the first page, or to skip
|
|
in increments of ten pages. Since VTEX doesn't go through CIO to
|
|
display on the screen, special characters (such as the clear screen
|
|
command) will not interfere with the display. VTEX has a pseudo-word
|
|
wrap (I'll explain later), and can delete the leading spaces from the
|
|
left margin (good for viewing files that have been PRINTed to disk).
|
|
VTEX also has string search capabilities and ASCII CR/LF handling. It
|
|
has been tested under both Atari DOS 2.5 (2.0) and SpartaDOS.
|
|
|
|
III. Running VTEX
|
|
|
|
From any Atari type DOS, use the binary load command and load the VTEX
|
|
executable file (VTEX.COM). The program will prompt for a filename.
|
|
Enter the filename to view and press RETURN. After VTEX opens the file,
|
|
the VTEX view screen will appear. At the bottom of the screen is the
|
|
VTEX status line. It displays the version number of the program, the
|
|
current page number of the file being viewed, and has an end-of-file
|
|
indicator. It also indicates if word-wrap or the delete leading spaces
|
|
options are active or not.
|
|
|
|
From SpartaDOS, you may specify the filename to view on the command
|
|
line. Simply type - VTEX filename <RETURN>. Under SpartaDOS, VTEX will
|
|
look for the filename on the command line. If it doesn't find the
|
|
filename there, it will prompt you to enter the filename (as it always
|
|
does under Atari DOS).
|
|
|
|
With either DOS, if VTEX encounters an error while trying to open the
|
|
file, it will re-prompt you for a new filename. If you wish to exit
|
|
VTEX at this prompt, press ESC. The program will then exit to DOS.
|
|
|
|
IV. Commands
|
|
|
|
Once VTEX is running, you have a number of commands to choose from. The
|
|
commands are explained below.
|
|
|
|
PAGE FORWARD
|
|
|
|
Press the down arrow key (without holding down the CONTROL key). VTEX
|
|
will display the next page in the file. As VTEX moves forward through a
|
|
file, it notes the position of the beginning of each page so that it can
|
|
move backward (or jump forward) directly to that page.
|
|
|
|
PAGE BACKWARD
|
|
|
|
Press the up arrow key (without holding down the CONTROL key). VTEX
|
|
will display the previous page in the file.
|
|
|
|
FORWARD 10 PAGES
|
|
|
|
Press <SHIFT> down arrow (without the CONTROL key). Note that because
|
|
of the way Atari 8-bit DOS's handle random access files, VTEX cannot
|
|
just jump to a page that it has not yet read in a sequential manner (see
|
|
the explanation in PAGE FORWARD). It doesn't know at what point in the
|
|
file the 10th page occurs, for example, until it has read pages 1-10.
|
|
Therefore, when you press <SHIFT> down arrow, VTEX will either:
|
|
|
|
1) Move forward 10 pages (if it has already read that far in the file)
|
|
|
|
- or -
|
|
|
|
2) Move to the highest page it has read (if less than 10 pages from the
|
|
current page)
|
|
|
|
BACKWARD 10 PAGES
|
|
|
|
Press <SHIFT> up arrow (without the CONTROL key). VTEX will either:
|
|
|
|
1) Move backward 10 pages (if the current page being displayed is
|
|
greater than 10)
|
|
|
|
- or -
|
|
|
|
2) Go to the beginning of the file
|
|
|
|
GO TO THE BEGINNING OF THE FILE
|
|
|
|
Press B to return to the first page of the file.
|
|
|
|
GO TO THE END OF THE FILE
|
|
|
|
Press E to ATTEMPT to go to the end of the file. VTEX can only go
|
|
directly to the end of the file if it has already read the last page.
|
|
Once the last page has been read (using the down arrow to page forward),
|
|
VTEX notes the position of this page so it can access it directly. If
|
|
the end of the file hasn't been read yet, the message NO EOF is
|
|
displayed in the status line.
|
|
|
|
DISPLAY THE CURRENT FILENAME
|
|
|
|
Press F to display the name of the file that is currently being viewed.
|
|
Press F again to see the normal VTEX status line.
|
|
|
|
WORD WRAP THE DISPLAY
|
|
|
|
Press W to turn on the pseudo-word wrap. A 'W' will appear on the left
|
|
side of the status line to let you know that word wrap is active. This
|
|
is not a true word wrap, so long words will hang over onto the next
|
|
page. VTEX will simply start looking for a space after column 31. If
|
|
it finds a space, it will break the line here and wrap the text at this
|
|
point. Pressing W again will turn the word wrap off.
|
|
|
|
Note that because selecting word wrap (or the delete leading spaces
|
|
option) will change the size of the displayed pages, VTEX resets the
|
|
file to start back at page 1 when either of these options are selected.
|
|
This allows the program to re-build its pointers to the beginning of the
|
|
pages (which will now be in different positions).
|
|
|
|
DELETE LEADING LEFT SPACES
|
|
|
|
Press D to turn on the delete leading left spaces option. A 'D' will
|
|
appear on the left side of the status line to let you know that this
|
|
option is active. Any spaces that would have appeared on the left edge
|
|
of the page are now gone. Also, the current page is reset to 1 (see the
|
|
note under the word wrap option for an explanation). Press D again to
|
|
turn this option off.
|
|
|
|
SEARCH FOR A STRING
|
|
|
|
Press S to search for a string. The program will prompt you to enter a
|
|
string. Type the string you wish to search for and press RETURN. The
|
|
program will start from the current page and look forward for the search
|
|
string. The search will stop when the program has found your string or
|
|
the end of the file has been reached. The function will not search if
|
|
the current page is the end of the file.
|
|
|
|
ASCII option
|
|
|
|
VTEX can optionally display ASCII carriage return/line feeds or carriage
|
|
returns alone as it would ATASCII carriage returns. This is useful for
|
|
viewing text generated on IBM PC's, such as many text files that are on
|
|
bulletin boards. Pressing A will toggle this option on or off. An 'A'
|
|
will appear on the left side of the status line to let you know that the
|
|
ASCII option is active. As with the word-wrap and delete leading spaces
|
|
option, the file will be reset to the beginning when this option is
|
|
selected.
|
|
|
|
LOAD A NEW FILE
|
|
|
|
Pressing L will make VTEX prompt you for a new filename to load and
|
|
view. Enter the filename and press RETURN. If the program encounters
|
|
an error while trying to open the file, the buzzer will sound and the
|
|
prompt will re-appear to allow you to try again. Pressing ESC at this
|
|
prompt will exit the option and let you continue to view the current
|
|
file. When a new file is loaded, VTEX operates as if it has just been
|
|
loaded (i.e. you begin at the first page in the file and all pointer
|
|
information must be re-created).
|
|
|
|
EXIT THE PROGRAM
|
|
|
|
To exit VTEX and return to DOS, press the ESC key. Note that if you
|
|
choose the search option, pressing ESC while the program is prompting
|
|
for the search string simply takes you out of the search function. This
|
|
is also the case with the load a new file option. Pressing ESC while
|
|
the program is prompting you for a filename will simply abort the
|
|
command.
|
|
|
|
V. SpartaDOS X Notes
|
|
|
|
If you are lucky enough to own a SpartaDOS X cartridge, then this
|
|
section will give you a few common sense ideas on how to best use VTEX.
|
|
|
|
First, it is very easy to make VTEX behave as though it is simply
|
|
another command by placing it on one of the active drives and setting
|
|
the PATH to look on that drive. I use a 256K 800XL, so I have an
|
|
AUTOEXEC.BAT file that does the following:
|
|
|
|
1) Set up a ramdisk as D8:
|
|
2) Copy VTEX up to the ramdisk and call it V.COM.
|
|
3) SET PATH=CAR:;D8:
|
|
|
|
With the path set up to look on the ramdisk for .COM files, I can now
|
|
execute VTEX from the command line without having to tell SpartaDOS what
|
|
drive it is on. Since it is on the ramdisk, it loads and begins
|
|
executing in a second. Also, by calling the program V.COM, all I have
|
|
to type to view a file is:
|
|
|
|
V filename <RETURN>
|
|
|
|
Second (and last), SpartaDOS X now handles the NOTE and POINT calls in
|
|
the same manner for both SpartaDOS and Atari DOS disks (it uses a byte
|
|
offset from the beginning of the file). What does this mean to the end
|
|
user??? It means if you use VTEX under the SpartaDOS X environment to
|
|
view an Atari DOS formatted disk, you will notice BIG delays when paging
|
|
backwards or forward. This is because SpartaDOS X must re-read your
|
|
Atari DOS file from the beginning each time a POINT command is given.
|
|
The solution is to copy the file to a SpartaDOS formatted disk before
|
|
using VTEX to view it.
|
|
|
|
I hope this is as useful to someone else as it has been for myself.
|
|

**********************************************************************
|
|
|
|
A day or two after I tried the program, Larry popped up in the Networked
|
|
messages from Orlando, FL! We have discussed VTEX, and found a minor
|
|
bug which he will fix in the next version. The bug: if you attempt to
|
|
run VTEX immediately after running BobTerm & some other programs, it
|
|
will turn the screen green and drop to the SpartaDos prompt. For now,
|
|
a re-boot will clear things up and all will be well!
|
|
|
|
I noted that Larry had not mentioned a 'suggested minimum donation' as
|
|
is usually the practice with ShareWare. His response:
|

|
|
|
I didn't put a 'minimum' amount in the DOC's for a donation (no
|
|
'maximum' either... HA HA). I do realize that times are tough.
|
|
However, any donations received are appreciated and will encourage me
|
|
to continue updating the current software that I have and to write new
|
|
stuff.
|
|
|
|
By the way, anyone wanting to donate can use my new home address (the
|
|
one in the DOC'S will work, but it is not as direct). The new address
|
|
is:

|
|
|
|
|
|
This utility has got to be one of the most useful utilities I have seen.
|
|
If you are like me, and search thru docs(Z*Mag?!) from time to time,
|
|
this will save you a bunch of time!
|
|
|
|
NOTE: Larry has moved to Orlando, FL. and can be reached on Moonbase
|
|
Alpha(407-578-2811), or any of the FoReM-XEP boards that network the

Don_Back(aka-Backdir & Repdir)
|
|
------------------------------
|
|
The other discovery that I made was a program that backs up directory
|
|
-entries- for SpartaDos 3.2! If you are an avid fan of SpartaDos, then
|
|
you are 'well aware' of the perennial problem of scrambled directories.
|
|
These happen for a variety of reasons, but happen they do! Especially
|
|
to owners of hard disks. Ask me, I *know!* <Grin>
|
|
|
|
I have tested this on floppies, and it seems to work rather well.
|
|
Haven't gotten up the nerve to erase one of my HD partitions for a
|
|
-really big- test, but if it does work, it could save you a whole lot of
|
|
hours of grief and work with DiskRX from ICD's SpartaDos Toolkit or the
|
|
sector editor in the BB enhancement by Bob Puff, or whichever sector
|
|
editor may be your favorite (read necessity).
|
|
|
|
Nearly everyone who has used SPD for any amount of time has done a -Dir-
|
|
and found a directory was trashed, garbled, crashed, etc. The first
|
|
program, -BACKDIR.COM- will back-up your -directory- for you.
|
|
|
|
The file name containing the directory data.
|
|
Where you want to put the Back-up Info. ^
|
|
The Directory you want backed-up ^ ^
|
|
^ ^ ^
|
|
The Backdir program ^ ^ ^
|
|
^ ^ ^ ^
|
|
The syntax is: -BACKDIR D2:*.* D8:>BAKD2>MAIND2.BAK-
|
|
|
|
You will have to run Backdir once for each Directory/SubDirectory that
|
|
you want to backup. The above would just backup the Main Directory of
|
|
drive D2. To backup Subdirectory -TEXT- on D2: you would run Backdir
|
|
again: -Backdir D2:>TEXT>*.* D8:>BAKD2>D2TEXT.BAK- And so on for each
|
|
Subdirectory which you want to backup.
|
|
|
|
To restore after a crash, you would run the second program, REPDIR:
|
|
|
|
The data file that contains the info for D2:Main Directory.
|
|
Where the backup data file will be found ^
|
|
The Directory you want to restore. ^ ^
|
|
^ ^ ^
|
|
The Repdir program ^ ^ ^
|
|
^ ^ ^ ^
|
|
REPDIR D2:>*.* D8:>BAKD2>MAIND2.BAK
|
|
|
|
Of course, this restoration will only be as good as the last time that
|
|
you backed-it up! If you have modified, deleted, or added files, you
|
|
will be back where you were when you last back it up! But at least you
|
|
may be able to recover most of what you had at that time! I would also
|
|
advise that you run Cleanup.Com by ICD from the SpartaDos Tool Kit to
|
|
make sure that all is well!

* BOOT-UP MENUS FOR ATARI 8-BITs by S.G. Wallace
|
|
=======================================================================
|
|
|
|
|
|
It's apparent from reading through the -pages- of ZMAG that some Atari
|
|
8-bit owners have very sophisticated systems. Hard drives, large memory
|
|
upgrades, special operating systems, and high speed modems can evidently
|
|
bring surprising power to an 8-bit.
|
|
|
|
Still, the 8-bit community is a diverse group with varying interests,
|
|
expertise, and financial status. For those opting to use their
|
|
computers -stock-, there is no shortage of fine features and software.
|
|
|
|
One of the most useful capabilities of a floppy disk based Atari 8-bit
|
|
computer is -booting- a program from a cold start. One of the most user
|
|
friendly programs to boot is a MENU program.
|
|
|
|
Picture this: Say you want to run an application, utility, or game from
|
|
a disk that has many programs stored on it. You turn on your monitor
|
|
and disk drive, and insert the disk. Next you flip the power switch of
|
|
your Atari XE, XL, 800, or 400 ON. After a few seconds you're presented
|
|
with a screen full of filenames contained on the disk, and an invitation
|
|
to select one for loading and execution. Depending on the menu you're
|
|
using, all you have to do to start the desired program is type a number
|
|
or letter for the file you want to run, or highlight the name by moving
|
|
a cursor. As you make your selection, the menu program in memory will
|
|
have served its purpose until next time, and will sacrifice itself by
|
|
running your chosen file.
|
|
|
|
This scenario can be reality with any Atari 8-bit computer and disk
|
|
drive. What makes it all possible is an AUTORUN.SYS file that either
|
|
CALLS or IS a menu program on the disk. Saved Basic menu programs may
|
|
be invoked at power-up by an appropriate AUTORUN.SYS file. Machine
|
|
language (ML) menu programs are simply named AUTORUN.SYS on the disk.
|
|
Either type will be started at boot-up.
|
|
|
|
Menu programs have been written...
|
|
|
|
1) in Basic that will load and run only Basic programs.
|
|
|
|
2) in ML that will load and run only Ml programs.
|
|
|
|
3) in Basic with ML routines that will load and run Basic OR ML
|
|
programs, AND print text files to the screen. An opportunity to
|
|
disable Basic when calling ML programs is offered.
|
|
|
|
4) Other menu programs are available with additional features like
|
|
deleting or adding files to the disk.
|
|
|
|
Of the types described above, #3 is my favorite. This type of menu
|
|
works best on XE, 800XL, or 600XL Ataris because Basic is built into the
|
|
computer. Even though the menu itself is a Basic program, the user has
|
|
the opportunity to turn Basic off if a ML program is called from the
|
|
menu. Basic files may be invoked from a Basic menu on 1200XL and 400/
|
|
800 models with cartridge Basic installed. ML files may be run with
|
|
cartridge Basic if the file doesn't load into memory used by Basic
|
|
(Basic can't be disabled except by removing the cartridge on these
|
|
systems).
|
|
|
|
Public domain (PD) software suppliers such as Software Infinity, Vulcan
|
|
Software, or Phantom's 8-Bit PDS often produce disks with menu programs
|
|
and self booting AUTORUN.SYS files on them. The menu programs
|
|
themselves are usually PD, so it's ok to copy them onto other disks in
|
|
your disk library or even modify them to your liking. Naturally, to
|
|
make other disks bootable, they'll have to have DOS.SYS and the
|
|
appropriate AUTORUN.SYS file on them.
|
|
|
|
A number of AUTORUN.SYS boot file makers have been available over the
|
|
years. Atari DOS 2.5 owners can create AUTORUN.SYS files that will load
|
|
and run any saved Basic program at power-up. Just use your SETUP.COM
|
|
utility which came with your DOS. Another AUTORUN.SYS maker was
|
|
described in two articles titled AUTORUN.SYS SECRETS and AUTORUN.SYS
|
|
SECRETS IN BASIC published by the now defunct ANALOG COMPUTING magazine
|
|
(Nov. 1988-issue 66, Jul. 1989-issue 74). The AUTORUN.SYS SECRETS
|
|
program files are still available for download on Delphi's Atari 8-bit
|
|
Utilities database.
|
|
|
|
Whether you write your own menu program, or obtain a PD version, it'll
|
|
bring a useful convenience to your computer system. You'll wonder how
|
|
you ever got along without it.

* CAROLYN'S CORNER by Carolyn Hoglin
|
|
=======================================================================
|
|
|
|
|
|
(This article is a reprint from the Mid-Florida Atari Computer Club
|
|
Newsletter of October, 1991.)
|
|
|
|
|
|
A glance at the calendar confirms that soon we Floridians should be
|
|
through with thunderstorms for a while. In the coming months, it will
|
|
be nice not to have to unplug after each session at the computer.
|
|
|
|
By the way, if any of you are not in the habit of pulling the plug on
|
|
your system, thinking you are safe because you have a surge protector,
|
|
let me assure you that a direct lightning hit will jump right over
|
|
whatever protection it offers. Even if you have pulled the electrical
|
|
plug, lightning can still enter through the phone line to your modem, so
|
|
you should disconnect that also. I know, it's a drag. But it doesn't
|
|
compare to replacing part or all of your system. And it could happen to
|
|
you!
|
|
|
|
Have you ever downloaded a text file from a BBS, examined it with
|
|
AtariWriter Plus, and found that it was all one paragraph with lots of
|
|
control M's and J's throughout? Well, those control characters are
|
|
ASCII-13 and ASCII-10, carriage return and linefeed respectively. Most
|
|
computers understand these codes. However, the 8-bit Atari computers
|
|
speak ATASCII (Atari-ASCII), which is just a little different. Here,
|
|
code 155 serves as both carriage return and linefeed.
|
|
|
|
Here's how to convert your file from ASCII to ATASCII: Be sure you are
|
|
in the -insert- mode. Then press [START-S] and type [CTRL-M][CTRL-J]
|
|
[RETURN] as the string to search for. Then press [START-R] and just
|
|
enter [RETURN], which means to replace with a null string. This
|
|
actually causes the program to delete the searched-for string instead of
|
|
replacing it with something else.
|
|
|
|
Now, start with the cursor at the top of the document. Press [SELECT-S]
|
|
to go to the first incidence of [CTRL-M][CTRL-J]. Press [SELECT-R] to
|
|
delete it and then [RETURN] to replace it. Repeat this procedure until
|
|
you reach the end of the document. If there two [CTRL-M][CTRL-J]'s in a
|
|
row, the cursor will already be on the second [CTRL-M] after deleting
|
|
the first set, so skip the [SELECT-S] and just press [SELECT-R] and
|
|
[RETURN].
|
|
|
|
Don't use the Global Search/Replace command [OPTION-G] here, or you will
|
|
find that all the [CTRL-M][CTRL-J]'s are deleted in a flash, but you
|
|
have no opportunity to replace them with [RETURN]'s.
|
|
|
|
Sometimes you have a file that was prepared to be viewed on the 8-bit,
|
|
40-column screen. When loaded into AtariWriter Plus, each and every
|
|
line has a return at the end of it. If you were to print the file as
|
|
is, you'd still have these 40-column lines on paper.
|
|
|
|
Here is one way to remove the extra returns: If you aren't already
|
|
using the full screen width, press [OPTION-C] and then -40-. Now press
|
|
[START-S]. When prompted for the search string, hold down the SHIFT key
|
|
and type [ESC][ESC], followed by [RETURN]. Then press [START-R] and
|
|
enter a [SPACE] followed by [RETURN].
|
|
|
|
These little tricks discussed here are quite useful when you are dealing
|
|
with relatively short files. If you have very long files, or multiple
|
|
files that need these conversion processes, it might be more efficient
|
|
to use one of the several available public-domain programs written for
|
|
this purpose.

* BEST OF 1987 - Z*NET SURVEY RESULTS Compiled by Ron Kovacs
|
|
=======================================================================
|
|
|
|
|
|
The following survey results were captured from a few Oasis BBS systems
|
|
running the Best of 1987 Survey.
|
|
|
|
The survey was created from the Best of 1987 Poll created in December
|
|
1986. All the nominees were listed by system users. Then I compiled
|
|
the survey from the entries and created the survey.
|
|
|
|
The highest amount of entries were listed in the survey for the users to
|
|
vote on. The accumulations of the systems captured, are included here.
|
|
A few of the questions have been deleted because they contained regional
|
|
and local information which is not of use in other areas.
|
|
|
|
Total amount of votes per question: 272

* ADVENTURES IN STRUCTURED PROGRAMMING - Part 5 by Michael Stomp
|
|
=======================================================================
|
|
|
|
|
|
V. THE FINAL FOUR
|
|
|
|
(Concluding a sketch of different methods of structured programming,
|
|
which follows a characterization of methods by P.J. Plauger in a series
|
|
of articles in Computer Language magazine.)
|
|
|
|
CHAOS-TO-ORDER DESIGN
|
|
|
|
As its name implies, this method is applicable in a situation in which
|
|
a sequence of data must be reordered. This usually means using a sort
|
|
routine. But it doesn't necessarily mean +writing+ a sort routine.
|
|
There are two reasons for not writing your own sort routine:
|
|
|
|
1) sorts are hard to get right, and
|
|
2) you can probably find a canned sort that will do the job for you.
|
|
|
|
TURBO BASIC XL, alas, doesn't have one built-in, but BASIC XL/XE has a
|
|
nice one, and it is pretty fast. Sort routines are also available for C
|
|
and ACTION!, and I have seen at least one in ML that is callable as a
|
|
USR routine from Basic. Only if all else fails should you consider
|
|
writing your own sort routine.
|
|
|
|
But first, you should consider the question of why you want to sort the
|
|
data at all. If you're never going to look at it again, there is no
|
|
need to sort it; if you don't care what order you consider the data in
|
|
the future, there is no need to sort it. If you think about it, the
|
|
only reason for sorting data is to make it easier to search for
|
|
something later. So, when considering the question of sorting, at the
|
|
same time consider the question of searching, which is discussed in the
|
|
next section, called,
|
|
|
|
ORDER-TO-CHAOS DESIGN
|
|
|
|
This method deals with the problem of looking up an arbitrary sequence
|
|
of items in an ordered collection of data. Operations on a collection
|
|
of data can be characterized as insertions (adding new data), deletions
|
|
(discarding existing data), replacements (discarding existing data and
|
|
inserting new data in its place), or reads (examining existing data).
|
|
Then there is the question of how to represent the data. It must be
|
|
represented so that 1) you know how to find it all, 2) you know when
|
|
you've found what you're looking for, and 3) you are able to do what you
|
|
want to do with the data once you've found it.
|
|
|
|
Suppose you have decided to store the data as records in a file; that
|
|
is, some number of bytes followed by an End-Of-Line character. You
|
|
would access it by a simple INPUT statement, and read it into a string
|
|
variable. You know when you have read it all because you will reach and
|
|
End-Of-File indicator. To search for something, you need a program that
|
|
reads the file one record at a time, knows which part of the record
|
|
holds the field you are scanning, and does a comparison between that
|
|
field and the search key. Scanning the file from front to back, then,
|
|
is pretty easy. Adding records is easy if you just add them at the end
|
|
of the file. Deleting records, however, is tiresome. You must either
|
|
rewrite the file to percolate down records after the deletion, or have
|
|
some way of marking certain records as deleted. If you do the latter,
|
|
you must plan to squeeze out the dead records periodically or you will
|
|
run out of disk space and longer access times become a problem. If you
|
|
expect to be doing a lot of deletions you should worry about this in the
|
|
initial design. Perhaps it might pay to allot a fixed amount of space
|
|
for each record, enough to hold the largest expected one. That would
|
|
make it easier to delete records: move the last record into the hole
|
|
left by the deletion and shorten the file by one record. If, on the
|
|
other hand, deletions never occur or are rare, you might switch to a
|
|
data organization that leads to fast, simple code for reads and
|
|
insertions but is miserable at deletions. It's a question of balancing
|
|
options against requirements; simplicity against performance.
|
|
|
|
If the number of records to search is small, access times might be fast
|
|
enough with the data in random order. However, with larger collections
|
|
of data, a sorted collection might be necessary to keep access times
|
|
reasonable. There are various search algorithms that are quite fast
|
|
when used on sorted data; binary search being one of the best. In that
|
|
method, you check the middle record of the collection against the search
|
|
key. Then you take the half that must contain the sought-for record (if
|
|
it exists at all) and split that in half. And so forth. In this way,
|
|
you can search a collection of N sorted records in Log2(N) steps.
|
|
|
|
There are many other possibilities for structuring data collections, and
|
|
many methods for handling searches. The literature is rich on this
|
|
subject. But first, you should consider just what your needs are, what
|
|
you want to do with the data, and pick the easiest method to implement
|
|
them. Preferably a method that doesn't require you to write the program
|
|
yourself. Think first, then code.
|
|
|
|
EASY-TO-HARD DESIGN
|
|
|
|
In this method one adopts the viewpoint that the structure of a program
|
|
should be most strongly shaped by normal, straight-forward conditions.
|
|
Errors, interrupts, limit violations, etc. are best handled as
|
|
exceptions, with minimum impact on program structure. The name derives
|
|
from the observation that writing a program innocent of exceptions is
|
|
relatively easy, so the harder problem of handling exceptions is better
|
|
deferred to last.
|
|
|
|
To be sure, you cannot just ignore errors; exceptions will happen.
|
|
Users will mis-type input data, printers will be left off-line, the
|
|
wrong disk will be in the drive -- all with amazing regularity. And if
|
|
you don't anticipate the occurrence of errors and exceptions your
|
|
programming language will respond to them by bombing the program.
|
|
Better to think about what could go wrong as you go along, and take some
|
|
countermeasures.
|
|
|
|
But it would be nice if one could do this error handling with the least
|
|
violence to the structure of the program. If you check for everything,
|
|
the error handling can end up dwarfing the straight-line code! There
|
|
are some simple techniques that can be of help.
|
|
|
|
After using left-to-right design to handle input data structure, adding
|
|
code to handle exceptions is pretty straightforward. To complete an
|
|
alternation, where you already have a chain of IF..ELSEIF statements
|
|
that look for alternatives, just add an ELSE clause to process all input
|
|
that fails the earlier tests. To complete a sequence, where normally
|
|
you would have no test, surround the processing statement with an
|
|
IF..ELSE to test if the item of data is okay. To complete a
|
|
repetition, all you have to do is make the loop test more suspicious,
|
|
and check for things like incorrect items or less items than expected.
|
|
Then, of course, you must decided what you are going to do if you find
|
|
an exception. If the input is being entered on-line by the user, the
|
|
easiest way is to report the error and prompt the user for the correct
|
|
data. The exception can then be handled locally. If the input is from
|
|
a file, you don't have that choice, and it may be necessary to abort the
|
|
input processing entirely -- after giving the user an understandable
|
|
diagnostic, however.
|
|
|
|
In Part I of this series, I presented a simple procedure for error-free
|
|
numerical input which can be called any time your program needs user
|
|
input. This procedure keeps all the error handling in one place, and is
|
|
not much more involved than a simple INPUT X. The same technique can be
|
|
used for more than just numerical input. To get a legal file name, for
|
|
instance, just put the input request and OPEN statement in a loop, and
|
|
don't exit the loop until you get past the OPEN statement without an
|
|
error. Otherwise, keep nagging the user for the right file name.
|
|
Keeping the address of the error handler the TRAP sends control to
|
|
within the same loop helps preserve the program structure.
|
|
|
|
Basic offers another feature that can help in some error handling; when
|
|
an error is detected, the line number where it occurred is stored in
|
|
memory location 186. In some cases, this can be used effectively to
|
|
continue program operation without loss of continuity. For example, to
|
|
handle the case when the printer is not on-line, one can do this:
|
|
|
|
TRAP #PRTERR:OPEN #1,8,0,-P:-:TRAP 0
|
|
|
|
Then, at the end of the program you have this error handler for the
|
|
printer:
|
|
|
|
#PRTERR
|
|
? -Check printer; press RETURN when ready-
|
|
GET A
|
|
GOTO DPEEK(186)
|
|
|
|
That will send the program back to the original TRAP statement, so the
|
|
OPEN can be tried again. A more general type of error handler can also
|
|
PEEK(195) to see the error number, and take appropriate action depending
|
|
on what error occurred.
|
|
|
|
It has been wisely observed that reliability cannot be retrofit. Easy-
|
|
to-hard design supposedly tells you what things you can defer until
|
|
later in the design process; error handling is not one of them.
|
|
Needless to say, most spaghetti coders like easy-to-hard design.
|
|
|
|
HARD-TO-EASY DESIGN
|
|
|
|
In his series of articles, Plauger focusses on synchronizing sequential
|
|
processes (he devotes two articles to the subject), as being a part that
|
|
is hard to get right, and so should be tackled first in the design
|
|
process. He says the only safe course is to minimize the places where
|
|
you must synchronize with another activity, such as an interrupt or co-
|
|
processor, write the code carefully, and keep it well separated from the
|
|
rest of the program logic. And do this first, before you write most of
|
|
the more pedestrian code.
|
|
|
|
Now, many might think all this is not relevant to the Atari 8-bit
|
|
programmer. What do we have to do with co-processors and interrupts?
|
|
The answer is: more than you might think. We do have some co-
|
|
processors, even if we haven't bought Bob Puff's new device. They are
|
|
called ANTIC, GTIA, and POKEY! They are working all the time, although
|
|
mostly invisible to us. The synchronization is handled automatically by
|
|
the Operating System and we usually don't have to think about the
|
|
subject at all. Unless we want to take advantage of the opportunities
|
|
offered.
|
|
|
|
These processes are synchronized with the screen display, through the
|
|
Vertical Blank Interrupt (VBI) at the beginning of each screen scan
|
|
(every 1/60 of a second), and the Display List Interrupt (DLI) at the
|
|
beginning of each scan line (about 1/256 of 1/60 of a second). A
|
|
programmer can insert his own routines, usually written in machine
|
|
language, to run independently of his main program and the
|
|
synchronization is taken care of by 'piggy backing' onto the Operating
|
|
System processes. Some of the uses this can be put to are: Player/
|
|
missal movement, player/missal animation, character animation, playing
|
|
music, multiple character sets, multiple screen colors, alarm clocks,
|
|
count-down timers, printer spooling, and many more.
|
|
|
|
More detail on this subject would exceed the domain of an article on
|
|
program design. Back issues of magazine contain many articles on using
|
|
VBIs and DLIs. The only point regarding hard-to-easy design is: get
|
|
those parts right first.
|
|
|
|
This concludes the series on structured programming methods. I hope it
|
|
has been of some help to you. I welcome any questions you may have.
|
|
They will provide subject matter for future articles.

|
A First Impression
|
|
February 1992
|
|
|
|
|
|
I was overwhelmed with excitement the day the UPS man delivered the box
|
|
from Computer Software Services. And I had very good reason to be.
|
|
After all, I had recently ordered one of their most technical devices,
|
|
the -Super E-Burner-. This device reads and programs EPROMS. That
|
|
stands for (E)rasable (P)rogrammable (R)ead (O)nly (M)emory. Whoa!
|
|
That's jumping in a bit too fast. How about we take a few steps back
|
|
and run over some basic concepts first? Ok, here goes...
|
|
|
|
Inside your computer is a ROM (Read Only Memory) chip which holds the
|
|
instructions that tell your computer what it is and how to operate.
|
|
This Operating System chip (OS ROM) is a permanent component which does
|
|
not need energy to maintain its data integrity. In other words, it
|
|
doesn't go blank when the power is removed like a RAM chip. The OS ROM
|
|
chip is programmed with instructions when it is manufactured, and cannot
|
|
be changed at a later time. An EPROM chip also retains its programming
|
|
when the power is removed, however, its programming can be changed. An
|
|
EPROM has a small window in the center of the top side of the chip.
|
|
Erasing an EPROM is done by simply exposing this window to a high
|
|
intensity UltraViolet light (Don't ask how, or we'll be here all day
|
|
talking about transistor gate depletion levels and photo electron
|
|
velocities). But programming (commonly called -burning-) an EPROM chip
|
|
requires a special device. Enter the Super E-Burner.
|
|
|
|
I had never seen a picture, nor heard a description of the physical
|
|
aspects of the Super E-Burner. All I knew was it plugged into the
|
|
cartridge port of the Atari 8-bit computer and was incredibly fast.
|
|
After tearing the shipping box open, I pulled out and observed a rather
|
|
odd looking device. The main unit of the Super E-Burner is a 5- x 5- PC
|
|
board which holds 1 power connection, 4 IC chips, 48 miscellaneous
|
|
electronic parts, 1 34-pin port, and 1 ZIF socket. What's a ZIF socket?
|
|
Well, it stands for (Z)ero (I)nsertion (F)orce. It's an expensive
|
|
socket that puts no pressure on the pins of chip. The socket has a
|
|
small lever on its side. After placing a chip in the socket, pressing
|
|
the lever down causes a metal plate in each hole to clamp down on the
|
|
pins thus making a solid electrical contact. Coming off the 34-pin port
|
|
is a two foot ribbon cable that connects to the cartridge interface
|
|
board. This board resembles the insides of a disassembled game
|
|
cartridge, and is used in a similar manner.
|
|
|
|
Despite the rather sparse and inadequate documentation which accompanies
|
|
the Super E-Burner, operating the device is quite simple. The cartridge
|
|
interface board is plugged into the cartridge port and the computer is
|
|
booted with your favorite DOS. (For reasons unknown to myself nor Bob
|
|
Puff, this device does not work properly with SpartaDOS X). Upon
|
|
entering the cartridge, the following menu screen appears:

|
|
| |
|
|
| |
|
|
+-------------------------------------+
|
|
|
|
From this menu, the EPROM size and programming voltage is entered. On
|
|
this subject, the docs say nothing more than, -Select the proper EPROM
|
|
type. An incorrect selection of types can damage your EPROM.- I
|
|
recommend you find some other references to help determine the proper
|
|
setting.
|
|
|
|
Once the EPROM type is chosen, the main menu is presented:
|
|
|
|
+-------------------------------------+
|
|
| Select Operation: |
|
|
|[R] Read EPROM [B] Burn EPROM |
|
|
|[V] Verify EPROM [E] Verify erase |

|
|
|[1-9] Disk directories |
|
|
| |
|
|
|Please Select > |
|
|
+-------------------------------------+
|
|
|
|
Although these menu selections are basically self explanatory, we'll run
|
|
through them quickly:
|
|
|
|
[R]ead copies the information from a programmed EPROM onto a disk file.
|
|
[B]urn writes information from a disk file onto a blank EPROM.
|
|
[V]erify compares the information on a programmed EPROM to a disk file.
|
|
[E]rase checks to make sure an EPROM is blank.
|
|
[N]umber sets the number of EPROMS to be burned from a single disk file.
|
|
[Q]uit exits to DOS.
|
|
[S]peed alters the programming speed for older and slower EPROMS.
|
|
[ESC] goes back to the previous menu.
|
|
|
|
Four stapled pages accompany the Super E-Burner consisting of: A title
|
|
page, a warranty page, a VERY oversimplified page of instructions, and a
|
|
page showing the orientation of different sized chips in the ZIF socket.
|
|
I immediately called CSS and asked Bob Puff, -Is this it!?- He assured
|
|
me they would be revising the documentation soon (more on that later)
|
|
and talked me through the necessary concepts and instructions.
|
|
|
|
Now that I've had the Super E-Burner for about a month, I find myself
|
|
rather comfortable with it. I have managed to backup every single ROM
|
|
chip in the house onto my Hard Drive (that's over thirty chips including
|
|
nine different Operating Systems for my 8-bit!) But the real fun of
|
|
owning an EPROM burner is firm ware modifications. By disassembling,
|
|
modifying, and rewriting parts of ROM code, I've managed to make my
|
|
130XE run in high speed mode with my US Doubler drives regardless of
|
|
what disk/DOS I boot; I've made a stock 1050, US Doubler 1050, and an
|
|
XF551 all respond to drive numbers higher than D4:; and I'm working on
|
|
modifying my SpartaDOS X cartridge to use the standard SIO vector so it
|
|
will work with a Multiplexer.
|
|
|
|
Within the documentation, a handwritten note says that CSS is working on
|
|
a built-in editor which will support XE memory. This would make the
|
|
Super E-Burner one of the most powerful firm ware devices I've seen. A
|
|
ROM chip could be read, disassembled, modified, and rewritten without
|
|
loading up any other programs. Bob said the revised documentation would
|
|
be included with the enhanced editor.
|
|
|
|
All things considered, I am very impressed with the Super E-Burner. It
|
|
is a well built, extremely fast, and (so far) reliable unit. In my
|
|
opinion, it is well worth the price. (Which as of this writing is
|
|
$169.95 + $8 S/H). Kudos to Bob Puff and the gang at CSS!

* DIGI-STUDIO INFORMATION
|
|
=======================================================================
|
|
|
|
|
|
Digi-Studio is a new piece of software for the Atari XL/XE series. It
|
|
allows you to play music using real sounds which have been digitized.
|
|
|
|
Digi-Studio comes with a keyboard player and tune player. The keyboard
|
|
player lets you use your computer keyboard like a piano keyboard to play
|
|
tunes, but using real sounds, rather than computer-generated noises as
|
|
is usually the case with this type of program. You can have 3 sounds in
|
|
memory and can quickly change between them while playing tunes. The
|
|
keyboard player has responsive keys so that the sound will only play for
|
|
as long as you hold the key down. Just like a synthesizer!! The Digi-
|
|
Studio disk contains many sounds for use with the keyboard player,
|
|
ranging from church bells, to pig grunts, to a baby crying, to screams,
|
|
and lots of synthesizer sounds. In fact around 25 sounds in all. Why
|
|
buy a synthesizer when your Atari can do the same?!
|
|
|
|
The tune player allows you to play pre-programmed tunes using any of the
|
|
available sounds on the disk. Five tunes have been included on the disk
|
|
for you to play.
|
|
|
|
Digi-Studio comes on a DS/SD disk, and includes a printed manual. It is
|
|
aimed at everyone, whether musically inclined or not! You may just want
|
|
to use it for fun, or compose a tune with it! The comprehensive user
|
|
manual makes it a joy to use!
|
|
|
|
Digi-Studio will only work on XL/XE computers with 64K RAM. No extra
|
|
hardware is required. The sound samples just play through your TV
|
|
speaker!
|
|
|
|
The full Digi-Studio package costs just 5 pounds in the UK, and 10
|
|
pounds for foreign orders, including printed manual, and shipping. All
|
|
payments must be made in UK funds (pounds sterling) and paid by money
|
|
order in sterling if you are ordering from a foreign country. Order
