Hypothetically, I know of a menu application that allows only authorized
users to update menu items.  That is to say, the F8 key will allow a
menu update, but F8 is not activated in the display file for
unauthorized users.

The program code probably goes something like:

   // If the user is allowed to change the menu, activate the F8 key
   if authorized_to_update;
       *in28 = '1';   // activate the f8 key
   endif;

   exfmt the_menu;

   select;
       *in08 wheneq '1';
            // process menu update

Notice, the programmer of the menu app assumes that only an authorized
user can press F8, and never considered that a hacked 5250 client can
probably set on the F8 key at will.
