[Message part 1 (text/plain, inline)]
Hello,



We are currently running gzip 1.9.7 on z/OS 3.1.

We plan to migrate to the z17 hardware and would like to know if there are any required actions to take for this product, such as upgrading or applying any fixes to tolerate the z17s.



Your assistance is greatly appreciated.



Thank you

Kind Regards,

I don't know. Perhaps someone from IBM would know.

I would upgrade to gzip 1.14, the current gzip version. It has fixes for 
z compared to gzip 1.9. You may also need this trivial patch to gzip 1.14:
