The default gzip distribution available on Rocket’s open source tool download page does not support z/OS 1.13. Users that attempt to run the default distribution on z/OS 1.13 will see this error:

“CEE3728S The use of a function, which is not supported by this release of Language Environment was detected”

A special distribution is attached here that works with z/OS 1.13. After downloading, transfer the file to z/OS in binary mode and unpack with command:

tar -xvof fileName

gzip-1.6-zos1.13_b0002.tar (630 KB)

It seems to be a not working tar file. Could you please check it?

Thank you very much!

My apologies Viktor. First tar was indeed bad. I replaced it with another upload and tested it. This one unpacks just fine in z/OS. Please try again.

Try zos 2.1 or later. We don’t support such an old zos version.
