Reading PF keys in REXX?

[imrexx]

Hi

i am doing a REXX program which executes recursively and it needs to stop by pressing a particular PF keys or quitting from the current screen. i.e. it starts executing by giving a macro in current EDIT screen. when user quits the current screen the REXX program shud stop.

Could any1 pls suggest how to check that in my program. if possible could any suggest with an example?

Thanks
Imran

The only keys that can do this are PA1 and PA2 because they cause an interrupt. PFkeys cannot do this.

Hi Frank

Thanks for your valuable information. Could you please give me an example to handle those interrupts?

You don't write code to 'handle' those interrupts. REXX doesn't recognize PA2 (an interrupt happens but REXX ignores it); on PA1 (ATTN) REXX halts and prompts the user at the keyboard.
