<p>Initial automated import</p> <p><b>New page</b></p><div>This directive is to used with the directive [[Z80:Directives:VAR/TVAR/TEMPVAR|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.<br /> <br /> == Syntax ==<br /> <br /> .define safe_ram $CED5<br /> .varloc safe_ram, 128 ; We have 128 bytes of safe RAM here<br /> .var byte, me_x<br /> .var byte, me_y<br /> .var word, me_dx<br /> .var word, me_dy<br /> .var byte, me_s<br /> <br /> Each time you use .varloc, you add a new possible area of memory to be used. For example:<br /> <br /> .define safe_ram_1 $CED5<br /> .define safe_ram_2 $F000<br /> <br /> .varloc safe_ram_1, 128 ; 128 bytes here<br /> .varloc safe_ram_2, 256 ; 256 bytes here<br /> <br /> .var 2, word_test ; Could go in either area<br /> .var 204, big_area ; Has to go in safe_ram_2<br /> .var 100, other_big ; Has to go in safe_ram_1, now!<br /> <br /> <br /> === Allowed inputs ===<br /> <br /> == Uses ==<br /> <br /> == See Also ==<br /> <br /> [[Z80:Directives:VAR/TVAR/TEMPVAR|var/tvar/tempvar]]<br /> <br /> {{lowercase}}<br /> [[Category:Z80 Assembly]]<br /> [[Category:Z80 Heaven]]<br /> [[Category:Z80 Directives]]</div>
