Assembly question

[slenkar]

this is fun

here is how I printed a block to co-ords 7,3

Code:

function FASTCALL drawthis() as ubyte asm LD HL,16384 LD BC,7 LD A,3 RRC A RRC A RRC A OR 7 LD L,A drawblokes: INC H LD A,254 LD (HL),A DEC BC LD A, B OR C JP NZ,drawblokes end asm end function drawthis() Print "done"

but if I move INC H to just before the jump command the screen goes a bit weird

Code:

function FASTCALL drawthis() as ubyte asm LD HL,16384 LD BC,7 LD A,3 RRC A RRC A RRC A OR 7 LD L,A drawblokes: LD A,254 LD (HL),A DEC BC LD A, B OR C INC H JP NZ,drawblokes end asm end function drawthis() Print "done"

EDIT
ohhh
INC seems to set the zero flag
