[273,42]	Offspring tasks in DECUS C.

CSPAWN.C	Contains a main() to test  cspawn(), which will spawn a task
		and wait for it.
		I use this a lot so applications programmers can call up
		MCR commands from inside their programs: you don't write
		fspool() when they can spawn to mcr... "PRI foo/DE" .

CHAIN.C		Equivalent routine to give a command and EXIT.
		Again some applications programmers think it useful,
		particularly for micky-mouse menu programs (yes virginia,
		people still do menus in 2nd generation languages!)
		that just dispatch to a worker program.
