Hi,

I see that my client uses REXX routines in VM machines to execute COBOL codes (you can't use JCL/ISPF services in VM machines). I do not understand the heads and tails of the REXX routines, also can't find any online manual/tutorial on the same). Can anyone guide me?

Hello,

At the top of the page is a link to "IBM Manuals". The REXX Language Reference and REXX User Guide should have the info regarding the REXX code you see.

People using your client's machine will have an understanding of how they chose to use REXX. Suggest you start talking with them.

Note however, that you should navigate to the z/VM library to get the right REXX publications for the VM/CMS environment. The directly available REXX publications are for the MVS/TSO environment.

In order to understand what is going on in the REXX routines, you should also familiarize yourself with the CMS and CP command languages. I bet there will be a lot of host command environment calls in those REXX execs.

Yes. True.

As you, I expect that there will be more to learn about the VM environment than the REXX code though. . .

Thanks to all the replies I received, I got a proper guidance on how to break through, and now I am comfortable with the said REXX codes.
Thanks again!
