Try:

	Lookup:
	parse arg myString
        ^^^^^

Notice the parse qualifier before ARG.  You should read the chapter on
PARSE-command; it's a really powerful command.

I have thought about this and it certainly should be possible to write an
ARexx `function server'.  One would call a function somewhat like this:

	result = server( afunctionname [, arguments] )

Server is a separate ARexx script which locates the functions and makes
the real call.  Performance might be quite bad, though.  Of course, every
primitive function could be in its own script, but having a huge amount
of small scripts is not my idea of fun.

I might try writing a function server when I have the time.
