Arexx and CEDpro - positively _the_ best combination for the Amiga! :-)

"arg" is short for 'parse arg upper'.  Use 'parse arg myString' and your
problem will disappear.

Arexx can call other scripts from within a script.

I just spent 5 minutes reading the manual, and creating this:

                              ---cut
/*rexx*/

/*test getstring*/

options results

getstring '" "' "My Test"

IF (result = "") | (result= "RESULT") THEN 
  okay1 "Need input, Stephanie"
ELSE 
  okay1 "you entered:" result
                               ---cut

Which duly said "Need input, Stephanie" if I just pressed return, or sent back
what I typed into the string requester.  [No, I'm not a transvestite, you
fools!  The quote is from Short Circuit.  Sheesh! :-/]

The way I originally read your message, you wanted to pass an empty string to
'DefaultTITLE' which, of course, you can't do :-(.  I guess you made a typo.
What application could call for a null defaulttitle?  :-)

Hope that's of use to you.
