Hey I’m kinda new to asm, and this problem is keeping me up all night
that i can’t solve it, so i’m hoping to get some help. for some reason the expression
or al, 11111111
when al = AA is giving me EF, instead of FF. And when i try
xor al, 11111111
it gives me 6D instead of 55. I don’t understand because i thought the or method would give me all ones and the xor would flip the bits.
11111111 is a decimal number (eleven million, one hundred and eleven thousand, one hundred and eleven).
You need a different syntax to specify that that’s a binary number; or, specify it as a hexadecimal number.
