This is a curiosity. I ran your code (after setting a value to volnbr and rmmcmd.volnbr) and the value of rmmout.1 was: EDG3201I THE ENTRY IS NOT DEFINED TO DFSMSrmm
I'm not sure I understand the scenario shown in your trace results where rmmout.1 could be equal to null while rmmout.0 is equal to 0. I realize you've snipped the REXX a little, but I tried and failed to force that result (using "DROP rmmout." or "rmmout. = ''"). I guess that's no help, sorry. Greg Shirey Ben E.
