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!
