Introduce how to write comments in .do files

[yuanyuan0314]

Hi~I hope I didn't misunderstand this prompt. For writing comments, I commonly use three different marks: /*/, //, . I think there are also some tricks to make the do-files readable. There are four things I usually do:

1. At the beginning of the do-file, I list the updated date, the goal, and the structure of this do-file.
2. I use a whole line of * to separate each "chapter" of the do-file.
3. I use // to write the purpose of some lines if it is not straightforward.
4. I use /**/ to save the results of some important lines below the lines themselves. For example, I will store the results of _merge for future reference without rerunning the codes.

Those tricks are very personalized. It might be too redundant. But it should be helpful for archiving finished projects. It might take a while to review a small part of the codes without comments.

Thank you!
