I have successfully ported the compress program to both MS-DOS and (believe it or not) VAX/VMS. The version I used was 4.0, as posted to mod.sources. My machine was a Zenith Z-171, which has proven quite PC-compatible. While hooks are in the code indicating that some effort was expended in attempting to take the PC into account, it's obvious from the name generation algorithm that it couldn't have ever worked on the PC, as distributed. (Do you know how DOS hates the name 'junk.c.z'?) I modified it to prepend a 'z_' to the filename; it still needs work, however, to handle multiple files and paths. But it does work...I've compressed files on Unix, shipped them to a PC and uncompressed them; both forwarded them to the Vax and recompressed before shipping to the Vax, and uncompressed them there. (And, of course, tried the reverse route, too.) -- Dave Ihnat Analysts International Corporation (312) 882-4673 ihnp4!aicchi!ignatz || ihnp4!homebru!ignatz

You can do an anonymous FTP. The files are in directory <info-ibmpc> . There are three files you need: compress.c compress.doc compress.make We're having some problems with our news server this afternoon, so I'll let you have the glory of posting this.
