FlashLocationMapPoints_Loop	33209	PUSH BC	Stash the locations count on the stack.
	33210	LD L,(IX+2)	Load the map co-ordinates for the current location into HL.
	33213	LD H,(IX+3)	Load the map co-ordinates for the current location into HL.

	33219	LD DE,22	Add 0022 to IX which is a safe place to land to find the next location.

CheckTerminator_Loop	33224	BIT 7,(IX+0)	Test bit 7 of *IX+0.
	33228	INC IX	Increment IX by one.

	33232	POP BC	Restore the locations count from the stack.
	33233	DJNZ FlashLocationMapPoints_Loop	Decrease the locations count by one and loop back to FlashLocationMapPoints_Loop until locations have been processed.
	33235	RET	Return.
