Re: A83: User defined variables
You could check out my tutorials? :)...but basically here is an overview:
The UDV start at 8265h, and go on until some damn place I never remember :)...you declare 'em like this:
#define bob 8265h
Now, the size of the variables depends on what you want...if you want it one byte then you could declare the NEXT variable like
this:
#define bob2 8266h ; OR....
#define bob2 bob+1
etc.
Now, you can only use a and hl for loading into and outta UDVs. For example, putting 4 in bob.
ld a,4
ld (bob),a
Getting variables outta bob2:
ld a,(bob2)
Easy, yeah?
Later,
James.
