Can we alter the command associated with a PF key using a REXX Utility.

Whenever a swap command is issued thro' a Function key, I want to do some operations before the swap command takes effect. But, since system commands take priority over the user commands, I am unable to work on this.

So, first I want to know what function key is associated to the swap command thro; rexx and change the swap command to my rexx utility, which performs the pre-processing operations and then issues the SWAP command.

Please guide me.

This shouldn't be a problem as you can interrogate and set the ISPF variables associated with the PF keys, these bieng ZPFnn. Here's some untested code that should assist you, assuming that the command is called PRESWAP and that ; is the command delimiter (you'd might want to save the original settings and then restore them):-

you're app will never see the swap command or any other that is defined in the command table. You'll need your own command table or to modify the current one.

Changing PF keys this way should be strongly discouraged. First, it affects all programs within the applid. 2nd, if the program abends, you can't clean up, 3rd it often assumes that users haven't redefined their keys. This type of situation is what command files and/or keylists (yuk!) are for.

Mike,

Of course, you meant

While I generally agree with semigeezer that this sort of thing is to be discouraged, there are times when I do it myself. It really depends on who will use the process. If its just for me, then I do what I want and worry about the cleanup myself. If it is for someone else, then I make sure I clean up after myself. Here is an example of some code I use to see if the user has PFSHOW ON set.
