I'm trying to do some work with Uedit and ARexx, and I'm having
some trouble.  Briefly the problem can be illustrated by the following
example.  I send a message containing "getfile()" to ARexx from uedit.
(That's the ARP file requester;  the necessary libraries are all loaded.)
ARexx gets the message and calls getfile(), which puts up a requester.
I choose a file "foobar" from the requester.  Since the result of getfile()
wasn't redirected to a variable or 'say' or anything like that, the value
"foobar" gets returned to uedit.  This is pretty much what I want.  However,
"foobar" gets returned to uedit in a new message, not in the reply to Uedit's
original message.  Then Uedit must reply to ARexx's message, then retrieve
the reply to the original message.

Schematically,


Uedit                                      ARexx

Message 1 --------"getfile()"--------->
         
          <-------"foobar"------------- message 2

message 2 reply ---<okay>------------->

          <--------<okay>-------------- message 1 reply


I want to condense this to


Uedit                                       ARexx

Message 1 ------"getfile()"-------------->

          <--------"foobar"---------------- message 1 reply
          

but I can't figure out how.  Uedit supposedly provides access to
RXFF_RESULT flag, but when I try to use it, it either is ignored or
crashes the machine.  I suspect the solution may be something like 
saving the result of getfile() to a variable, then using some reply
or return function to get that result back to Uedit.  I can't seem 
to find out what that might be, though.
