/* Shell.rexx
	Demo of the "captive shell" technique
	requires Csh 4.01a or later */

shell command "run shell -c rxrec CSH"
call delay(500)

	a = "say hello"
	shell CSH
	
	do until upper(a) = "QUIT"
	
		interpret a
		parse pull a		
	end

shell rexx "shell CSH 'quit'"

---cut----line----

	I had to do a lot of:

alias CD cd

	To get this to work.  (Why are the shell builtins cased, if the OS 
isn't ???) However the CSH port sticks around afterwards due to a bug in the
shell, so this is really only a demo of what could be done.

	Hint, try stuff like:

b = "ram:"
cd b
say b
