Does anyone out there know the details of the compression algorithm(s) used by the CRUNCH/UNCR programs? I would like to incorporate UNCR functions into my IBM (mainframe) utility, but have been unable to decode the crunched files. The older versions of the program pair claimed to used LZW, but its a completely different variation from ARC. The latest version of CRUNCH uses GEL(?) compression. Perhaps someone can send me the source for CRUNCH/UNCR formerly distributed with version 1 I believe (and no longer distributed with version 2, sigh.)
