Not sure if this was pointed out before, but DDNAMEs are required by z/OS access methods, not JCL. There is no reason these or dataset names need to be arguments just because REXX is used instead of JCL.
DDNAMEs are a pretty nice feature of z/OS! So you *don't* have to pass a bunch of (potentially very long) file names. DDNAMEs can be thought of as a limited form of environment variables. sas On Wed, Jul 11, 2018 at 10:51 AM, Hobart Spitz <orexx...@gmail.com> wrote: > Andrew wrote: > > ... > > >The connection between program (DDNAME) and resources (dataset etc.) is > nice too.
