Recently read UC / OS-II books, it is inevitable to read source code during reading. I chose UltraEdit, or a novice. I found that the text editing software using such a text is also a pleasure.
Today, when you edit a text file, you need to use the function of automatically generating the line number. I have found it with Google. I didn't find the answer (maybe it is a keyword I have selected). The result was inadvertently found in the answer. In fact, it is very simple, the menu bar "block" -> "switch block mode", there are several new items in the "Block", know how to do it!
Don't say simple, I am a rookie.
