(The following from memory; I'm not retesting): In order to generate a tape compatible with non-IBM systems, I used RECFM=U, BLKSIZE=5120, the latter being the default given by "man tar" on a non-IBM system. Then I never found a non-IBM system with compatible drives, but I was able to read it back and uncompress and untar it on the creating z/OS system. In a Rexx exec, I piped tar | compress | [descriptor piped to SYSUT1 of ATTCHMVS IEBGENER]. Tar now can write its archives to Classic data sets, but I doubt it can deal with uncatalogued data sets. I'm now using CD-ROMs instead of tapes. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
