Hi,

Could you please let me know what are the major differences between REXX on TSO environment and REXX on Z/VM environment.

Also could you please provide any document contains these differences and specific zVM REXX concepts.

Thanks,
Kalyan.

In here, in the Reference, you will find concepts.

Rexx was first on VM/CMS. There's lots of rexx stuff "out there". What is the particular problem you are encountering?

Thanks Bill,

Actually i know TSO REXX and i have to work on z/VM REXX. So i want to know how zVM REXX concepts will be different than TSO REXX.

Appreciate your help if i get the differences in these two.

Thanks,
Kranthi

I don't think it's in the rexx itself that you'll find so many differences, but in the "environments" that you "address" for instance, and in the file structures - the non-rexx stuff that you are used to using in rexx on z/OS.

If you are using CMS (which I assume you are) you'll find the XEDIT editor much more powerful, don't limit yourself to what you know, type help and get reading.

The rexx itself on VM/CMS is rexx, much as the z/OS variety. That won't be your learning curve. Start with those VM rexx manuals in the link. Look for example execs/macros at your site. Just get to grip with "address CP", "address CMS" and the minidisk file-structures (and look up in a manual what the filetypes mean, the numeric part).

Hi Bill,

These manuals which you gave are really helpful. Thanks for that.

I want to learn how we can trigger REXX execs with console commands, messages, external interrupts. Please let me know if we have any manuals with such examples.

Thanks,
Kalyan
