CONVERSION FROM BINARY TO HEXADECIMAL

each 4 bits (a nyble) makes up a digit of hexadecimal.
each byte (2 nybles) has 2 digits.
How I did it for speed was to have a string with value of '0123456789ABCDEF'
say al holds value I want to convert:
mov ebx,OFFSET HEXstring
or eax,0Fh
add ebx,eax
mov al,[ebx]
al will hold ascii charactor!
to do high digit aswel:
push ax
{do low charactor}
pop ax
shr al,4
{do low charactor but returns high char}
this should help you but i didnt have the time to go deep on this right now, if it doesnt help reply to this.
