Usage of set /p:
set /p variable=prompt string:
Output the prompt string in the console; assign the user's input (ended by pressing Enter) to the variable; note that the user's input is on the same line;
Its own characteristics determine that it can not wrap lines;
<nul assigns an empty string to the variable to shield the user's input, so it seems that it just displays the prompt string on the console without requiring the user to input; at the same time, note that there is no carriage return passed, so there will be no line break;
In this case, the variable can be omitted..
Abbreviated as set /p=prompt string<nul

set /p=1<nul set /p=2<nul Why does using "<nul" make it not wrap and display characters? How to explain it??
