Why I like the IBM 3090
|
|
|
|
First, there's the wonderful operating system, VM/SP,
|
|
which has so many advantages! Here are some of my favorites!
|
|
|
|
1. All of your files are in the same directory, you don't have to
|
|
worry about subdirctories and other nonsense.
|
|
|
|
2. For file names, not only do you get a file name, but you also get a
|
|
file type and a file mode, with the name and type each being an
|
|
astounding 8 characters, plus a 2 character file mode, way more than
|
|
I ever had on my Apple II.
|
|
|
|
3. If you create a small file, it automatically makes sure it takes up
|
|
one 4K block on your disk, so you can add up to 4K of data to the
|
|
same file and not take any more disk space! WOW!!!!!
|
|
|
|
4. When you get an account you get an entire cylinder to yourself, an
|
|
amazing 465K, which is more than my 5 1/4 inch, single sided,
|
|
low density PC disk.
|
|
|
|
5. If a FORTRAN file is too long (250 lines) to compile on your disk
|
|
because the temp files fill up your cylinder, all you have to do is
|
|
unlink your A disk, create a big temporary disk, attach that as your
|
|
A disk, attach your old A disk as another disk, copy the source file
|
|
to the new A disk, then compile it.
|
|
|
|
6. You never have to worry about background processes, redirection, or
|
|
piping because the 3090 doesn't have any! Or command histories!
|
|
|
|
7. Or here (WSU) we are privileged to have RESLIM, which makes sure that
|
|
you don't use any more CPU time than you want to or have to.
|
|
|
|
8. We also have system administrators who also make sure we don't use
|
|
more CPU than we have to, not to mention they tell us what we can
|
|
and can not do, and what they think they legally can and can not do,
|
|
such as maintenance on our accounts to make sure there is nothing
|
|
wrong with any of our personal files.
|
|
|
|
9. If any files have sat in your reader/mailbox too long, they will
|
|
automatically be discarded for you.
|
|
|
|
10. And finally, all of the useful on-line help! All you have to know
|
|
is the name of the command and whether it is in CP or CMS or SOFTWARE
|
|
or one of the other help menus, and you can get a great description
|
|
of that command and some examples how to use it like you would want
|
|
to every day!
|
|
|
|
Not only is the operationg system fantastic, they have an awesome full
|
|
screen editor, XEDIT. Boy, it's quite a step up from EDLINE on my PC!
|
|
Just look how powerful it is:
|
|
|
|
1. If you want to move your cursor to the middle of the screen, all you
|
|
do is hold down the arrow keys until you get there.
|
|
|
|
2. If you wanna delete a whole bunch of characters in the middle of the
|
|
line all you have to do is hold down the DELETE key until they all
|
|
magically dissappear.
|
|
|
|
3. If you wanna insert something, all you do is hit the INSERT key and
|
|
type in what you want, unless it's too long for that line, then all
|
|
you gotta do is split the line where you want by using the PF11 key,
|
|
which, if you are on a VT100, is just an ESC minus sign.
|
|
|
|
4. After you do any commands in that neat prefix area, your cursor
|
|
almost always goes back to the command line at the bottom of the
|
|
screen.
|
|
|
|
5. You never have to worry about anything nasty like tab keys, there are
|
|
no tab stops by default (unless you wanna set them)
|
|
|
|
6. And, unless you tell it otherwise, XEDIT always creates fixed length
|
|
lines of 80 characters, so if you ever want to put more stuff on the
|
|
same line sometime later, there is room for it!!
|
|
|
|
Add to all of this such things as COBOL, disk linking, EBCDIC
|
|
character set (I mean who says J should follow I?), and even
|
|
some awesome graphics capabilities, and you'll have to agree that the
|
|
IBM 3090 is the system for me!!!!
