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.

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? >And, adding extra options to something is always allowable.

Conway's Law. Grrr... We haven't discussed APF authorization under the hypothetical JCL replacement. Is Pipelines available under z/VSE? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
