This is a sub-page of Crystal Beans from Dungeon Explorer.

Overview

The ShortSwitch() (at 0x0089CF) and LongSwitch() (at 0x0089E9) functions are used to simulate the switch statement in C for the objects subtype.

They both work the same way excepted that the ShortSwitch() function uses 16-bits pointers to jump to the destination and the LongSwitch() function uses 24-bits pointers.

These function do not return to the instruction following their call but rather to the instruction following the calling function.

Example

CALL SomeFunction
; ShortSwitch will return here after jumping to its target
.

SomeFunction:
  CALL ShortSwitch
