9 | ; BX: Menu event (anything from MENUEVENT struct) |

10 | ; SS:BP: Menu library handle |

19 | ; There are two ways to use MENUEVENT: |
---|
20 | ; |
---|
21 | ; 1. If the program needs two different menus, include the definition of the MENUEVENT structure below, |
---|
22 | ; instantiate with members that point to the routines that make up the menu. |
---|
23 | ; |
---|
24 | ; 2. If the program needs only one menu, %define MENUEVENT_INLINE_OFFSETS before this include file, |
---|
25 | ; and define (through EQU statements) each of the entry points as offsets from a base address. |
---|
26 | ; |
---|
27 | |
---|
28 | ; |
---|
29 | ; If user level idle processing is desired, %define this symbol and .IdleProcessing will be called. |
---|
30 | ; Otherwise, the code and structure entry will be omitted. Note that INCLUDE_MENU_DIALOGS requires |
---|
31 | ; the idle processing (if that is the case, it is turned on here). |
