(Does JES3 require UNIT and SPACE, lest DSN not exist?) <SNIP> I know that it does require the DSN (whether by catalog or by volume specific allocation). I don't recall it requiring space. However, I normally use SPACE=(TRK,1) as someone else demonstrated. Using IDCAMS will get you a JCL error, because SETUP makes sure that the DSN is actually available -- it doesn't see the dynamic build.
