Steve,

Does this do what you need?

$ TYPE CMD*.COM

DISK$DATA1:[FELDMAN.VMS.DCL.SPAWN]CMD.COM;1

$ SPAWN/NOWAIT @CMD_SUB.COM
$_WAIT:
$ WAIT 0:00:01
$ NUMSUB = F$GETJPI("","PRCCNT")
$ IF (NUMSUB.GT.0) THEN GOTO _WAIT

Alas no, because that would mean that CMD always waits for
CMD_SUB to finish.

What I want is for CMD to do "spawn/nowait @CMD_SUB" and
then exit when called like this:
$ @CMD

or like this:
$ spawn
$ @CMD

But I want CMD to wait for CMD_SUB when called like this:
$ spawn @CMD

or like this:
$ spawn /nowait @CMD

Does this do what you want? (Put commands for the CMD.COM in part 1
and those for CMD_SUB.COM in part 2.)

$ TYPE CMD2.COM
$ IF (P1.EQ.1) THEN GOTO PART1
$ IF (P1.EQ.2) THEN GOTO PART2
$ SPAWN @CMD2.COM 1
$ SPAWN @CMD2.COM 2
$ EXIT
$
$PART1:
$ WRITE SYS$OUTPUT "PART 1 HERE"
$ EXIT
$
$PART2:
$ WRITE SYS$OUTPUT "PART 2 HERE"
$ EXIT
$

It's late. I hope I got it right! :-)

The only problem I see is that you don't get the prompt string for the
first command you run after the SPAWN/NOWAIT run. 'Hope that's not a
problem!
