Sender: SuperSS SS, Area: ANSI Title: Production of special qmd 4 color sender, etc. Sending site: Sun and Moon Guanghua Monday, September 15, 2003 15:44:36, site mail Each article begins with some specific information Sender: user id nickname, message area: xxxx Title: xxxx Sending station: Sun and Moon Guanghua xxxx year xx month xx day xx:xx:xx week, site letter The first few lines are slightly different when investing directly. If you want to "modify" the content of this part, there is a way. The main principle is to use the cursor to position *[H and use the new content overwrite the original content For example, the user ID starts from the ninth character on the first line, so you can use *[1;9H to position the cursor there. Then overwrite the original one with the content you want. For example, replace the original pure white ID with a color coded color ID. Other content can also be covered in the same way Here are some frequently asked questions First, the following content is moved up, so you cannot simply use "*[1;9Hxxxx" to solve the problem. It should be done after the coverage is completed. After that, the cursor is restored to the position before positioning. This requires the storage and restoration of the cursor position *[s and *[u In other words, it should be written as "*[s*[1;9Hxxxx*[u" The second is the problem of length inconsistency. The overwritten content is shorter than the original content, leaving a little bit uncovered. If you happen to leave half a Chinese character, it may cause garbled characters. The covered content is longer than the original, which will affect the following. If there is any text, you should generally calculate the length and fill it with spaces or use *[K to delete the cursor in the line. Later content and other methods to eliminate the impact The third is the problem of error coverage in long articles. There is no way to do this. Only 23 lines of content are displayed on one screen. If the language is covered, The sentence is not within the 23 lines, including the original sender's lines, so the original content cannot be overwritten. It’s still a small matter. The key is to scroll the screen. When this line of code is explained, the first line on the screen is no longer the sender, but The code *[1;9H will still work and will still cover the content there. This may cover some words in the text. It will cause trouble for others to read, so don’t use this kind of qmd when posting long articles. Fourth, when someone else uses qmd to quote your article, it will still be overwritten, possibly because the sender they see is your id. There is no way to cause trouble. Fortunately, qmd is not quoted by default. In addition, there is no cursor control under the Web, so Web users cannot be taken care of. Note: *[s and *[u control characters are not supported under Unix. Instead, *7 and *8 are used. Therefore, users of this type of qmd under Unix systems It seems that there will be problems. Some people suggest using *7*[s and *8*[u to store and restore the cursor position to make the versatility better. I don’t use it. Unix cannot test After all, this kind of qmd has too many problems. Use it with caution. Source: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 6 Zhang J]
