I am having problems with passing values back from UDFS
the following is an example

***Procedure library
procedure Valid_input
parameters message
**SAY Screen
@ row,col say message get answer
 read
return(ans)

*** calling program
set procedure to library
.
.
.
ans = valid_input(message)
**end of example

I can use it with a "do valid_input with "message" but I am writing an
application that is heavily dependent on UDFs so I don't want to have
to devise a  clumsy work around..the way I use now is global varibles..

any sugestions are greatly appreciated
replies can be sent directly to me and if there is any interest I'
ll post a summary

thanks
