On a system-wide basis, you can modify APL Data Interface II (APLDI-II) to alter the way users leave APLDI and return to an invoking program, such as the Information Center Facility.

The unmodified version of APLDI requires the user to press the END PF key twice when responding to an APLDI prompt. Pressing the END PF key the first time (or entering a null line) terminates the APLDI "SELECTION:" prompt. Pressing the END PF key again saves the user's work in a CONTINUE workspace, terminates APL, and returns to the invoking program. After you install this modification, users can press the END PF key only once to leave APLDI, save the workspace, terminate APL, and return to the invoking program.

To make the modification, enter APL and change line 2 of the GF function in APLDI as described in the function ICQINP of workspace ICQUPDTS.
