Cancel Versus Exit

The basic dialog flow for CA Gen functions conforms to CUA standards. CUA treats the cancel and exit commands as two distinct activities, each having a standard or common function key dedicated to it.

• Under CUA, the Cancel function (F12 by default) lets you back up to the previously displayed panel. Repeated use of the Cancel function lets you back out of the function one panel at a time until you reach the menu from which you selected the option.
• The Exit function (F3 by default) causes the function you are executing to stop; you are returned to the menu from which you selected the option. Repeated use of the Exit function lets you back out of the CA Gen menu hierarchy one menu at a time until you reach the ISPF main menu.
• Full-screen pop-up panels, used for selection lists and option-specific parameters for Code Generation functions, do not allow the use of the Exit function. To return to the previously displayed panel without selecting an item, you must use the Cancel function.

The Exit command is not supported here, because it applies to the application as a whole, not to the immediate panel being displayed. After you have canceled the pop-up, you can Exit from the function.
