Many thanks to those of you who replied to my request for file compression software. In brief, most responders use PKZip, are happy with it, and have never used anything else. PKZip is available from PKWare, who also sells a data compression library. The library is $295 and has no runtime royalties; a distribution license is required for PKZip and is priced on an individual basis. PKware's phone number is (414)354-8699. The other frequently mentioned package is LHArc, which is available free even for commercial applications. It is available from wuarchive.wustl.edu under mirrors/msdos. This is the package that I have chosen, and it is adequate for my purpose whi0 bytes down to about 300000, and LHarc fits the bill. I have heard that a C-callable version of LHarc exists, but as yet I've been unable to find it. If anyone has information on this, I'd appreciate hearing about it. Robert Jung's ARJ was also recommended by several people and is available for sale as a callable subroutine from Turbo C, Turbo C++, Quick C and Prime ANSI C. Special thanks to Robert for his assistance. Another freelance programmer, Graham Toal, has written some callable C functions for file compression/decompression. He will post them to alt.sources when they're finished. Finally, PAK251.exe is available from wsmr-simtel20.army.mil as shareware. It also works fine. Thanks again to those who responded.

Actually, the C and Turbo Pascal source is avilable. The three places I'd suggest to look are: Simtel20 , Chyde or Garbo (sorry, I don't remember the IP node), or wuarchive.wustl.edu. At chyde, its in /pc/source (I think).
