It is suggested not to use int20 to end the program, some software will take over it, how good it is to use int3(cch).

To understand the knowledge in one aspect, it is best to be able to buy two or three similar, appropriate computer books. Appropriate books have comprehensive basic theoretical knowledge. What others provide are just skills in a certain aspect. I think accumulating fragmented skills is not very suitable for beginners because a few lines of text from others may contain basic knowledge in various aspects. Others are not patient to explain the basic theory to you. Without basic theory, it is easy to take many detours and spend time. One should have basic books to cooperate with learning, and then it is easy to accept others' skills.
