I'm a newbie in assembly language, I would be glad if someone could help me out in a couple of questions that I had below:
1. When I'm in debug (under dos), and let's say I type a100, followed by some assembly instructions. The last 2 instructions are INT 21 and INT 20. When I tried tracing it, the instruction "INT 20" is no where to be seen, instead, I see "NOP" instead. I also noticed that after executing the intruction "INT 20", my cs:ip jumped to somewhere else.
