Hardly forgiven in that many desktop systems (which Rocket may have used for packaging) provide uncompress but not compress because of (expired) patent restrictions. Even worse, some provide gzip but misname it "compress".
Hmmm... I believe gzip uses the Deflate algorithm and jar probably embeds Deflate. But I suppose the wrappers are incompatible. In extremis, Rocket could have zipped (or jarred) a .tar file and specified jar followed by tar to extract. Hmmm... Is jar base z/OS, or separately ordered, or separately priced? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
