- Synopsis
-
- TY either extracts or types files which have been stored in
- compressed form using SQ.COM or one of its variants. TY
- requires DOS 2.0 or later.
-
- Description
-
- TY operates on the Huffman encoded files created by SQ.COM or one
- of its many variants. TY has two functions: it will either
- extract a compressed file or it will type that file to
- standard output. The use of standard output allows the target
- file to be given an arbitrary name or path, rather than simply
- the name stored within the 'squeezed' file. There seem to be
- two different squeeze formats in use, distinguished by the
- initial signature word (FFFA and FF76) and this program handles
- both of them. The date and time of the output file are set to
- that of the input file in extract mode. The date/time information
- in the FFFA format files is ignored.
-
- Command Line
-
- ty[/E][/H] [template....]
-
-
- /E - perform the extract function, creating the output
- file in the current directory.
-
- /H - print a header identifying the current operation (useful
- in typing many compressed files at once)
-
-
- template may contain wild card characters and multiple templates are
- allowed. If no template is supplied, the default template
-
- *.?Q?
-
- is used.
-
-
- Examples:
-
- ty/eh -- extracts all files matching the default template
- printing the name of the output file as it is
- decompressed.
-
- ty/h -- type all of the compressed files is the current
- directory, printing a header line identifying
- each file before it is operated on.
-
- ty/e readme.qqq -- unsqueeze one file named readme.qqq, probably
- producing readme as a result.
-
-
- ty rdme.qqq >x -- extract rdme.qqq and produce file x. note
- that X may be an arbitrary pathname.
-
-
- Why?
-
- After running out of disk space on a project, I began to use
- the SQ.EXE and USQ.EXE public domain programs, however, they
- take up too much disk space to be a real solution. I then
- discovered a program to type a compressed file (again, public
- domain) but it was also too large. It seemed natural to combine
- the extract and type functions in a small .COM program and here
- it is. The resulting .COM module takes less than 1400 bytes and,
- as a plus, seems much faster than USQ.EXE or NUSQ.COM.
