Gil To answer the one question
But GIMZIP/GIMUNZIP require SMP/E RACF authorization (WHY!?) which may be an obstacle in some environments. Because many of us asked for IBM to do this. We found that groups outside of Sysprogs were using SMPE to verify fixes. We did not want them altering the environment. So the facility classes were created. Also, I think there were some audit issues within some shops. So this was done to also support them.

I believe a zip archive containing exactly one file, compressed with the Deflation algorithm, can be extracted with gzip. >On Tue, Jun 25, 2013 at 10:31 PM, Kurt Quackenbush wrote: >> >> Have you heard of ServerPac?

So, thanks for providing me a lead to information that I may someday find useful. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
