question on using mov [di], 0

[ninjarider]

if i remember correctly you can use a register to point to a memory address

im currently using this code

Code Select Expand


stosb
xor ax, ax
stosb
dec di


whenever i use this code

Code Select Expand


stosb
mov [di], 0

i get an error message about the mov instruction

I am using the masm32 9 with the 16-bit linker. the code is setup using .186

why am i getting the error message?

That's because the assembler doesn't know if you want to store a byte or a word at that address. You have to specify it as follows:

mov byte ptr[di], 0
mov word ptr[di], 0
