Good Afternoon

I was hoping someone could explain to me how to properly code for an
instance when the user presses the Page Up or Page Down key while in a
subfile.

I have the following in my DDS

A DSPSIZ(24 80 *DS3)
A PRINT
A CA01(01 'MAIN MENU')
A CA02(02 'NEXT QUERY')
A CA03(03 'PREVIOUS')
A PAGEUP(81 'PAGE UP')
A PAGEDOWN(82 'PAGE DOWN')

This allows me to utilize *IN81 and *IN82 however it seems like my code is
only run when the keys hit the end of the subfile.

That is normal where SFLSIZ <> SFLPAG. IBM i handles paging between
pages that are already loaded, and only returns control to your code if
it reaches the end (or beginning).

For example, I have code that should evaluate a Y/N field in a subfile
record and turn on a protect indicator when one of the Page keys are
pressed.

If you set SLFSIZ = SFLPAG then you will get control on every press of
the Page keys, but now you must keep track of where in the PF you are as
you READE going forward and READPE going back. Or store the keys in an
array that you manage, or, or, or.

Please note I am coding in RPG III.
