My guess is that resolution of dynamic symbols can differ each time they are interpreted, In my JCL coding, I use refer-backs so that that any dataset is evaluated only once in the JCL. Further references to that dataset do not use the dynamic symbol.

Thanks Sri, I did not know about SYSSYM=ALLOW. But that raises the question why NOT always allow system symbols in every batch initiator? Allowing them just seems like a no-brainer to me, but then I'm just an application programmer who expects to be able to use all of the available tools to get the job done.

Peter,

Not all shops SYSSYM=ALLOW defined. So if your jobclass is NOT defined to allow symbols, the symbols will not be translated. However with program EZACFSM1 will translate all the symbols defined to the system.


Thanks,
