- USQ.COM
-
- USQ.COM is an assembler version of the standard Unsqueeze program,
- written in C. The advantages of this version are MUCH faster execution, same
- syntax for operation (including multiple files and wildcards), and much
- smaller size (only 2k!).
-
- To use this program on files which have been compressed by SQ, simply
- type:
-
- USQ filename
-
- Where filename is the full name and extension of the file you wish to
- decompress.
-
- You may also use the multiple file option, and you may also specify a
- different drive for the output files. As well, you may just type:
-
- USQ
-
- This will place you into a command line driven mode, indicated by a '*'
- on the screen. All normal filename combinations will work now, but the disk
- drives will be reset before any operations are preformed. This allows you to
- change disks without returning to CP/M.
-
- As mentioned earlier, this program will also accept wildcards. You may
- wish to decompress, for example, all .AQM and all .DQC files on drive A, and
- put the destination files on drive C. To do this, you would type:
-
- USQ *.AQM *.DQC C:
-
-
- Possible errors:
-
- While unsqueezing, you may encounter some errors. The most common will
- be BDOS errors of the bad sector nature. Everyone knows how to handle these!
-
- Less common will be messages like "Illegal decode table size", which
- usually indicates that the file in question is not a squeezed file, but
- appears to be. If a file is not a squeezed file, but is included in a
- wildcard specification (like *.*!), the file will not be altered, and the
- message "is not squeezed. Ignored" will appear.
-
- A very uncommon error will be "Checksum error.". This error indicates
- that the file does not match the original. It is usually caused by either an
- undetected BDOS error, or possibly a file transmission error. Try to obtain
- another copy of the file, and attempt the decompress again.
-
- Differences between the C version and this one:
-
- None of the "-" switches operate in this version, as I have seen no call
- for them. Directed I/O will not work, but using the command line mode, and a
- public domain package like "EX 1.21" will give you the same effect for input.
- Wildcards can usually solve the problem, though, since files that are not
- squeezed are ignored.
-
- Disclaimer and Warning:
-
- While this program has been tested, no liablity will be assumed for its
- operation, or lack thereof.
-
- Feel free to use this for personal use, but if you wish to bundle it with
- other software, or sell it itself, please contact me for more information.
