Now I want to make a qmd that hides IP. I use "Esc[x;yH" to jump to line x to achieve it. I found that when x 0, the title line 2 on the screen will be overwritten, and the line 1 "Sender..." will not be overwritten. When x increases from 1 to 22, the rows specified by x will be overwritten in turn. At x 23, the IP happens to be hidden At x 24 hours, line 1 "Sender..." is overwritten When x is from 24 to 48, the rows specified by x are overwritten in sequence. When x 49, the title line 2 on the screen will be overwritten again I am using cterm. I think the principle of loop coverage should be related to the maximum number of lines in cterm. but 1. Why is the line "Sender..." not overwritten in the first loop? But it can be covered in the second loop? 2. Why is the turning point of the third cycle 49, not 46? SuperSS SS mentioned on Thursday, March 27, 2003 18:18:25 1 23 is easy to explain The screen is 24*80 *[n;1H Position the cursor to the nth row and column 1 And when all the code of your article, including qmd, is displayed, the system automatically adds the source in the following line, that is, press Enter first. In this way, when the last code of your qmd is positioned on the nth line, the source will be displayed on the nth line. If you locate line 23, then the source is on line 24, which is just covered by the blue information bar. Since the cursor cannot move out of the screen *[0;1H is the same as *[1;1H But after 24, what I encountered was different from yours. Maybe it has something to do with which setting. If 24 is located at the last line, the source should be displayed on the next line, but there is no line 25. At this time, the screen will automatically scroll up one line, that is, the first line moves out of the screen, and the source is in the last line, which is also covered. 24 and above are the same as 24 This is the case after experiments with cterm2000, fterm2.4, and sterm2.03 So I think it may be related to some settings. I can't display the loop. Your problem below cannot be explained at the moment.
