You have to change your subfile to processing by page (where page size
equals subfile size).  That way, when PgDn is pressed, return will be
passed to the program and you can do error checking.

I have a basic DSPF/SFL-processing question which I hope will be answered
here.  (It's not Code400 specific)

this is how it works now:
----------------------------------
I have a SFL with 50 records.
Screen display's topline (1st page).
I enter option '3' on the 3rd record
then I scroll to the 4th page
I enter option '2' in the 2nd record
finally I press enter inputoptions are checked/processed
user get's an error the option on first page is not valid

When the user uses pageup/pagedown, he is scrolling through the subfile
without entering the program.

but

I want an errormessage when user enters '3' followed by pageup/pagedown
without processing

QUESTION:
Is it possible to check the options when the user users pageup/pagedown
- without 'processing' the program logic
- without using specific function keys (i.e. 'F7/F8')
- without using the 'Values' keyword in DDS like this:
               ZSEL           1A  B  7  2VALUES(' ' '1' '2' '4' '7')

a good example of what I want is the behaviour of the 'Work With Members'
-panel.
When a user enters '10' and presses 'PageDown', he get's a message that
this is not a valid option, however when entering a correct option, it is
not processed immediatly.
