PF key handling in IMS DC is done by the user application. If you don't want your application to handle them simply don't program them.

In my online PL/I program i have implimented scroll down(PF-8) and scroll up(PF-7) logic whenever there is end of table i want to disable PF-8 since there are no more records to display. how should i do that?

In the program check if PF8 key pressed and also end of table reached then display message " LAST PAGE" or "NO MORE DATA" some message onto screen.

If you want to dynamically display PF8 ON and OFF in the screen then you need to do this differently.

Let us know what you want to do

Presently i am displaying "END OF TABLE" on the screen when there is end of table i.e. SQLCODE = 100 my logic is perfect but problem here is whenever he is pressing F-8 (three to four times) after end of table conditon the program is abending so i want to disable F-8 key at end of table, so that even after he pressess F-8 after the reaching end of table the program should not abend........

Whenever you reached End of Table and displayed screen with END OF TABLE message you can use SPA or some hidden field on screen or on temp db2 tables to store an indicator indicating that already END OF TABLE reached.

If PF8 is pressed again then in program check what is the indicator value if its set then display some message 'NO MORE TO DISPLAY' some kind of message.

The scenario which you explained should be handled within program.

which will be efficient SPA or hidden field for indicating that END OF TABLE is reached

What technique is efficient really depends on how exactly you can do and also what is allowed in your shop. like hidden field may not be used in many shops, SPA will be ideal choice. Again any method requires coding and testing effort to make sure what u expected is working.

If you already use a SPA in your MPP you will always read it at entry of your application and insert it before leaving it so why not store it there.

I do not want to disable the function key in FORMAT but i want this to be done through APPLICATION PROGRAM (PL/I) based on END OF TABLE conditon.

So..........this discussion could be closed; program it and use the SPA like you told us.
