z80:Directives:VARLOC
From Learn @ Cemetech
Jump to navigationJump to search
This directive is to used with the directive var/tvar/tempvar to create a bunch of labels which point to variables in areas of memory without you having to manually calculate the offsets in memory yourself.
Syntax
.define safe_ram $CED5 .varloc safe_ram, 128 ; We have 128 bytes of safe RAM here .var byte, me_x .var byte, me_y .var word, me_dx .var word, me_dy .var byte, me_s
Each time you use .varloc, you add a new possible area of memory to be used. For example:
.define safe_ram_1 $CED5 .define safe_ram_2 $F000 .varloc safe_ram_1, 128 ; 128 bytes here .varloc safe_ram_2, 256 ; 256 bytes here .var 2, word_test ; Could go in either area .var 204, big_area ; Has to go in safe_ram_2 .var 100, other_big ; Has to go in safe_ram_1, now!
