Mapinfo/ArcInfo communication (answers to questions and updates from time to time)

Today, someone asked me, How familiar are you with MapInfo?
I can't give it up. I can't say it is proficient, but it is still quite skillful. After all, it is the most used. But for example, I can't tell it, it's just a function in the menu, I didn't dig for the Extension function, but there were a lot of things to do on Mapinfo, and the most simple editing of the dot and line surface. How do I say? Oh, just add a dot and draw a straight line, which will explain the problem? I admit that I am not proficient in MapInfo and ArcInfo, And I am speechless, So I open such a post.
Here we hope to share with you the usage of MapInfo and ArcInfo and ask and answer questions in the form of a post. If you have any questions, please leave a message below, if you know the answer to the question, please leave a message below. If you have a better solution, you are more welcome. After all, my personal abilities may not be enough to answer the question, so I hope you can help. I will sort out and update this post from time to time, and summarize the problems and answers that you have encountered below. If you think that the answers to the questions are very classic, I will organize them into a post. For more information about the question, see the answer. I hope you can exchange and make progress together. Thank you.
