[CMS-PIPELINES] Variable scope (again, probably)

[Paul Gilmartin]

I just answered a question here with mention of:

  ||──STREAMSTate───ALL──variable──────────┘

Then I do a "PARSE VALUE variable WITH ..."

... But now I recall problems I had because if a (Rexx) stage is
running asynchronously variables it references are defined in the
nearest nested static REXX.  So is there any guaranteed way to
pass the result of STREAMSTATE to PARSE?

The answer may necessarily be, "No", because there's an inevitable
TOCTTOU condition with an asynchronous stage.

Thanks,
