Hello. Just have a newbie-at-asm question :-)

Lets say I have 

int i = 256;

I'd like to copy the high byte into the low byte, and save the low byte
as the var 'i'.  Sorta like this:

asm(" movb %%ah, %%al
    : "=al" (i)
    : "a" (i)
    : "%eax");

Can I, using the output registers, just save AL to the variable i, so
that I just get the low byte?



Thanx in Advance!
