  Sometimes. The spawn function is preformed by DCL (the CLI).	If
the detached process is started with loginout then it will have a CLI
and be able to use LIB$SPAWN.

  If you start the process with RUN/DETACH PROGRAM.EXE the process
does not have a CLI and cannot use LIB$SPAWN.

  If you start the process with RUN/DETACH
SYS$SYSTEM:LOGINOUT/INPUT=PROGRAM.COM where PROGRAM.COM can be a
one-liner of "$ RUN PROGRAM", then the LOGINOUT which runs before
your program maps the CLI and your program can use LIB$SPAWN.
