This thread concerns replacing JCL, not replacing or enhancing TSO.  There are
many utilities available via JCL which are not TSO commands nor Pipelines
stages.  I've used SMP/E extensively.  I do not expect and scarcely want to see
SMP/E refactored as a TSO command or a Pipelines stage.

Ouch!  Conway's Law.  Grrr...

LINK, LINKPGM, and LINKMVS are all different.  LINKMVS provides the interface
closest to Assembler Call or JCL EXEC.  It is widely used.  z/OS LINKPGM 
provides
a different interface.  It's less widely used, but there are examples in 
SYS1.SAMPLIB.
The closest compatibility would be achieved by adding LINKMVS (LINKOS would be
a better name) to z/VSE Rexx, even if it is simply an alias for z/VSE LINKPGM.  
This
would leave a compatibility issue for the few programs that use z/OS LINKPGM.
The problem hasn't arisen; it's unlikely.

What does PARSE SOURCE report on z/VSE?  Might a programmer case this out
and issue ADDRESS VALUE 'LINKPGM' on VSE and ADDRESS VALUE 'LINKMVS'
on z/OS?

Mostly good.  Except when Rexx is executed with IRXJCL, OUTTRAP effectively
traps DD SYSTSPRT.

Ouch!  Conway's Law.  Grrr...

We haven't discussed APF authorization under the hypothetical JCL replacement.

Is Pipelines available under z/VSE?
