Thanks for the excellent help for my first two questions (I must have been
sleeping when I read the description of ARG!).  The sample code you show
above is something I also tried, as it is given in an example in the CEDPro
manual; unfortunately is doesn't do what I want.

The example passes a space character as the DefaultValue.  If the user types
a string, the space is appended to their input.  To see this effect replace
the last okay1 call with:

okay 1 "you didn't really enter: [" || result || "]"

My application needs the input string without any bogus appended space char.
As I mentioned I currently strip the trailing blank off, which is good enough
I suppose.  But I was hoping I could pass an empty as the DefaultValue so
that I would get the user's input string returned without any bogus tailing
blank.

PS. Thanks to everyone else who has replied to my query as well!
