>Don't you have to pass NEWDD and OLDDD in the call ?< Apparently not... the NEWDD and OLDDD DD statements are present in the JCL for the job step, and they were found correctly (as was DELDD). Presumably, I could have dynamically allocated those datasets as well, but that wasn't necessary in my situation. Regardless, I didn't need to pass the DDNAMEs as parameters.
Thanks, David
