Anything after "foo.rexx" becomes a single argstring which can be parsed.
Try this foo.rexx:
/* ... */
parse arg w1 w2 w3 w4
call alpha(w1, w2, w3)
exit
alpha: procedure
say arg()
say arg(1)
say arg(2)
say arg(3)
return
/* end of foo.rexx */
Now try:  (1)   rx foo This is a little test.
and       (2)   rx foo "This is a little test."
(Surprised?)
