But GIMZIP/GIMUNZIP require SMP/E RACF authorization (WHY!?) which may be an obstacle in some environments.

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
