1. Type Y in the CHANGE ISPF DEFAULTS for the USER and/or ADMINISTRATOR field on the Enroll Identification panel to access the ISPF parameter options panel. The ISPF parameter options panel is the ISPF/PDF panel ISPOPTA.

   The ISPF parameter options panel contains categories of defaults. Choose the categories of defaults you want to change.

   Notes for changing a USER's default profile:

   1. You cannot access the ISPF parameters options panel if you are in split-screen mode. If you type a Y to change a user's ISPF defaults, and your screen is split, you will receive an error message.
   2. You cannot split the screen when you are using the ISPF/PDF defaults dialog to change a user's ISPF defaults.
   3. Do not use the KEYS command to update your own keys when you are customizing a user's ISPF profile. If you are in the process of changing a user's ISPF profile, modifications to the key settings using the KEYS command are made to the user's profile. You can use the KEYS command to update your keys at this time.
2. Type over the default information you want to change. Press the END PF key and you are returned to the default selection panel. You can then select another set of defaults to change.
3. After making all your updates, press the END PF key to save the changes.

Although you might have made changes on several panels, the system saves the changes only after you press the END PF key while the ISPF parameter options panel is displayed. You can cancel all of your changes by typing CANCEL after the OPTION arrow on that panel.
