DOCUMENTATION FOR UNSQZ.COM version 1.10 as of 09/16/84
PRELIMINARY
UNSQZ is a new unsqueezer. YET ANOTHER ONE! WHY?????
Well, I have my reasons. Here they are:
1. I used to use UNSQ14, which, like USQ119, has the nast habit of attempting
to unsqueeze everything in sight if told to usq *.*...
2. Many times I want to get rid of the squeezed file after unsqueezing.
3. I may want to selectively unsqueeze 5 out of 10 files.
4. I may want to unsqueeze to a different drive and/or user area.
5. I may not want to use NSWP to do 1..4 above.
So, I wrote UNSQZ. A few words about UNSQZ and how to use it:
The following are legal command lines:
A0>unsqz *.* ;unsqueeze all squeezed files
A0>unsqz b7:*.* ;usq all in B7:, output to current area
B3>unsqz c: ;same as "unsqz c:*.*" (*.* can be ommitted)
B3>unsqz a5: c4: ;usq all from A5 to C4
A2>unsqz a: $e ;usq all, erase after unsqueezing
A2>unsqz a: $q ;query before unsqueezing, allow skipping
A2>unsqz a: $qe ;same, but ask before usq AND before erase
UNSQZ can be aborted at any time by pressing ^C (CONTROL-C) on the keyboard,
except while waiting for a yes/no response. the abort will take effect JUST
BEFORE the next USQ action, ie after the current job has been completed and
(if specified) the source file has been erased.
Please report any problems or suggestions to the SENECA RCPM 214-553-1363
Fixed in UNSQZ10: problem unsqueezing files larger than 16k
Fixed in UNSQZ11: buffer alignment error, inability to detect non-squeezed
*.?Q? files
NOTE:
The resulting output file is identical to the squeezed file, up to and
including the EOF marker. The remainder of the last sector is undefined.
CRCK may produce different results. Other than for cosmetic reasons, there
should be no reason to change this.
