- 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.
