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)
