[comp.binaries.ibm.pc.d] .Z compression pgm for IBM

EGRIFFIN@MIAMIU.BITNET (02/08/91)

I have been trying to convert .Z files that are supposed to be GIF files.  I
have been attempting to use 2 different programs, unsuccessfully.  I found out
about these 2 programs (U16.exe and Compress.exe (from comprs16.arc @ simtel20)
via a document @ ux1.cso.uiuc.edu called compression.new, which lays out most
of the current compression methods, specifying the compression method name, the
compression extension (e.g., .zip, .arc, .Z, etc.), the programs that are used
to create files with that compression method (and uncompress those files), and
where those compression utility programs can be found on internet.
    While this document seems comprehensive and helpful (I highly recommend it)
it isn't helping me figure out what's going wrong as I try to use U16.exe and
Compress.exe.  For all I know, I am simply missing 1 parameter (e.g. -x, -i, or
something like that) when I execute the program(s).
    If someone has successfully converted .Z format files so that they can be
used on an IBM AT, (which is what I have), PLEASE HELP ME.
 
Thanks in advance!

Rename compress.exe to uncomp.exe, then do:  uncomp filename.ab   if the
name of the file is filename.abZ.  I can't remember if it will accept the
Z, but it does work without it.  Btw, tell whoever you got the gif's from
(if that is what they really are), they gif's use the same LZW compression
technique that compress uses, and you won't gain much (more likely lose) space
in the process.
