All right, this is what I did.  Here are 2 examples:

	ld hl,menu_table

DoMenu:
	blah,blah,blah

menu_table:
	.db 3
	.db "My menu",0
	.db "Goto label 1",0
	.db "Goto label 2",0
	.db "Goto label 3",0
	.dw label_1
	.dw label_2
	.dw label_3

label_1:
	blah,blah,blah

label_2:
	blah,blah,blah

label_3:
	blah,blah,blah

.end


This example shows the run-in to the menu.  Here is another:

	ld hl,menu_table
	call _clrLCD
	ld b,1
	ld a,1
	cp b
	jp z,DoMenu
	cp nz,ret

DoMenu:
	blah,blah,blah

menu_table:
	.db 3
	.db "My menu",0
	.db "Goto label 1",0
	.db "Goto label 2",0
	.db "Goto label 3",0
	.dw label_1
	.dw label_2
	.dw label_3

label_1:
	blah,blah,blah

label_2:
	blah,blah,blah

label_3:
	blah,blah,blah

.end


The whole point of these are that you don't call the menu.  You have to either
do a run in to it or jump to it.  Simpe enough?  If not, just reply with more
info.  I did the best I could.
