When I first read the IL, many instructions couldn't remember, you print the following two forms, prepare for quick check before the case! Initially I read IL, it is doing this. Later, I taught others to compile, and others must print this form first. You can also get information on your own text. However, maybe I organize this form, it is more convenient!
