Hi, I've started looking at z/VM and came across this, in my opinion, rather strange call:
Code:
st1 = "/EXEC ABC "||fn ft fm ||"(/"
"PIPE Stem s1.",                                                 
"| Spec "st1" 1 1-4 nw",                                           
"| > WORK FILE Z",                                                   
"| CMS"   


The program ABC does not return a value, it just does an EXIT, so how do 'st1' get set and to what? I'm also not quite sure what the slashes around the EXEC ABC are doing. No GLOBALVs that I can see.
I have checked both the VM REXX User's Guide and the zVM REXX Language Reference, but didn't find an explanation there.
My apologies is this is basic VM stuff, but I haven't touched VM for ages.

Code:

is just a plain REXX assignment statement

That's embarrassing - of course it is. But now I see what's going on, thanks
