If you don't have/like streamx, and your situation calls for a new job (not
passing info to a pre-existing job), then you can do almost anything with a
command  file that uses :echo to build a job.  With a little help from
!hpstreamedby, you can have the new job :tell its results back to whoever
streamed it.

You have to watch out for a few things, as in:
echo !!RUN SIC0300.PROG.MERRY; INFO= & >>*TJ

echo : '!PF_INVC' >>*TJ

You need the '!!RUN' to pass '!RUN' to the job.  Just one '!' it tries to
resolve as a variable at echo time.  On the 2nd line, ':' works as the 1st
line of a continuation.  The single '!' in '!PF_INVC' works because it is ok
to have echo resolve the variable, so the job just sees a hard-wired
literal. To make it real variable to the job,  add another '!'.  But if the
'!' is followed by a character that can't be part of a variable name, then
don't double it.  Etc. Etc.

I haven't come across anything you can't do this way, though a really long
job would  be more trouble than it is worth.

I can post some full examples if anyone is interested.
