Message:

Space optimization, added option to inline offsets for MENUEVENT structure, for situations (such as the XTIDE bios) where only one menu is needed. Ifdef'd change (set in main.asm) so either method can be used.

     23; There are two ways to use MENUEVENT:
     24;
     25; 1. If the program needs two different menus, include the definition of the MENUEVENT structure below,
     26;    instantiate with members that point to the routines that make up the menu.
     27;
     28; 2. If the program needs only one menu, %define MENUEVENT_INLINE_OFFSETS before this include file,
     29;    and define (through EQU statements) each of the entry points as offsets from a base address. 
     30;    Entry points must be within 256 bytes of the base (only a byte is used to pass the offset).
     31;
