Registers - beginner
I've been reading online tutorials about Assembly but there's one thing that is still unclear to me. Is there only one piece of each register (AX, BX...)? If so, why aren't other programs affected if they're using the same registers I change in my own program? Like if they're using CX for a loop...- Leijonamieli

Difference between int and long
If the size of int is 4 bytes and long is also 4 bytes, what makes long different from int? 1 byte can have 2^8 different values so 4 bytes would be 2^32, but I thought long was 2^64. Or have I missunderstood something...- Leijonamieli
