Hello,
I am developing a system using Forms 3.0 and I REALLY need to perform
some screen Input Output, something like display at 1,10 'Hello' and input varx.
I cannot perform this operations directly using forms.
I would like to use C and Forms user_exits to realize this operation.
Right now I am working with OS/2 but I would like to port my software
to different platforms. (I know that i would probably need to rewrite
the C code for each different platform).
I wrote a very simple user exit to print 'Hello' on the screen but I
obtain a system violation and the OS aborts the entire form.
The manual specifically warns about SCREEN I/O conflicting with forms
I/O but I would like to know if anybody has had the same problem (using
any platform) and if somebody has solved it.
Thank you very much for your cooperation.
