Description:
|
|
|
|
PROARC is a Prodos based utility designed to provide the
|
|
user the ability to "archive" his 5.25 disks to a Prodos
|
|
file in a compressed format. A secondary function gives the
|
|
user the ability to read an input Prodos file and generate
|
|
a cooresponding compressed output file. When archiving disk
|
|
data, the resultant output file will be of the following
|
|
format:
|
|
Filetype = $F7 Filename format = XXXX.DSK
|
|
|
|
When archiving a file, the resultant output file will be of
|
|
the following format:
|
|
|
|
Filetype = $F8 Filename format = XXXX.ARC
|
|
|
|
This output filename (XXXX) may contain up to 11 characters,
|
|
not counting the 4 character filename extension (.DSK/.ARC).
|
|
The extension may be entered manually by the user or the
|
|
program will automatically append the proper extension for
|
|
him.
|
|
|
|
These resultant files can then be placed on a mass-storage
|
|
device for archival purposes or uploaded to your favorite
|
|
BBS for disk/files transfers. The degree of compression
|
|
realized from archiving a disk or file will vary according
|
|
to the source data. In case of disk archival, the output
|
|
disk file can be minimized if the source disk is not too
|
|
fragmented. Fragmentation results from repeated file
|
|
deletions and allocations. The user can "defragment" a
|
|
normal DOS 3.3 or PRODOS disk by copying all the files off
|
|
to a freshly formatted disk. The resulting defragmented disk
|
|
is then archived by PROARC to achieve minimal output file
|
|
size. Certain file types will realize significant file size
|
|
reductions when archiving them, especially text files. In
|
|
any case, any file size reductions will affect transfer
|
|
times in BBS uploads/downloads.
|
|
|
|
The user can then "de-archive" these resultant files back to
|
|
their original forms. When converting a DISK file back to a
|
|
floppy, a low-level format is automatically performed on the
|
|
output disk. In the case of an archived file, the original
|
|
file's attributes are internally saved so the unarchived
|
|
file will be identical to the original file.
|
|
|
|
Minimum system:
|
|
|
|
Any Apple II series computer with at least 64k and one 5.25
|
|
floppy drive.
|
|
|
|
Some other features:
|
|
|
|
If a Prodos compatible clock is detected in the system the
|
|
time is displayed in 12-hour format at the menus.
|
|
|
|
If no clock is availiable the ability to set the system
|
|
DATE is provided so the user can at least date stamp his
|
|
output files.
|
|
|
|
Basic.system is protected by PROARC, therefore all normal
|
|
Prodos commands are availiable to the user within PROARC.
|
|
|
|
Floppy drives MUST be running out of Slot 6. Drive 1 or 2
|
|
may be selected for DISK archival/unarchival.
|
|
|
|
All file accesses follow the normal Prodos file hierarchy.
|
|
|
|
At the menu screens, CONTROL-A will toggle upper/lower case
|
|
screen output.
|
|
|
|
Program exits through Prodos's normal Quit code.

Please distribute this program as freely and fluently as

possible. Let's campaign for widespread Prodos-based BBS's.
