This is quite interesting. Learning assembly.

Good stuff!!!!!!!!!!!!! Useful, thanks!

Learning

Sure enough, it's really amazing..................

楼主，还可以再省2字节！
in al,71h
ROR al, cl ; change to SHR al, cl
and al, 3 ; delete this line
add al, '0'
int 10h ; write char al, teletype mode
In the above program segment, "ROR al, cl" is to rotate right by 6 bits, and "and al, 3" only takes the last 2 bits. But AL is an 8-bit register, 6 + 2 = 8. If it is changed to SHR to shift right by 6 bits, the first 6 bits of AL will be naturally cleared, that is, there is no need for "and al, 3" to limit to the last 2 bits! In this way, 2 bytes can be saved.

I don't know if it's easy to use,.,.,., thank you first~

This thing is just what I want!

It's really to view not to change,? I'll try it

?It just flashes by. Why? How to use it? Anyone who knows, please tell me. Thank you?

Now, is there any senior here who is online and can tell me?

Great stuff! First, pull down. Thanks to the LZ!

I've been studying for a long time and still don't know how to use the superuser~~~//
