I wrote this really quick to test variable stuff, but it doesn't work.  It is
designed to show each of the variables in past the "Variable" Label in
sequence. It should show zero for the third nuber, and then 255 for the
fourth.  After assembling it (usgard, which would explain the usgard.h file) I
ran it, but it gave me odd numbers.  I don't know if it is just an error like
with the "ld h,0 / ld l,a" or what, but could someone please help.  (sorry if
I sound like an idiot to those of you who know what you are doing :-) , but
i'm just trying to figure out how this works)  thanxx again.  Here's the
source:

#include "usgard.h"

	.org 0
	.db "Variable Test",0

	call CLEARLCD
	ld a,(Variables)
	call &Bob
	ld a,(Variables+1)
	call &Bob
	ld a,(Variables+2)
	call &Bob
	ld hl,&Variables+2
	ld (hl),255
	ld a,(Variables+2)
	call &Bob
	ld a,(Variables+3)
	call &Bob
	ld a,(Variables+4)
	call &Bob
	ret

Bob:
	ld hl,0
	ld ($800C),hl
	ld h,0
	ld l,a
	call D_HL_DECI
Wait:
	call GET_KEY
	cp K_ENTER
	jr nz,Wait
	call CLEARLCD
	ret
	
Variables:
	.db 242,5,0,3,2,111
