It's too complicated, I can't understand. Can you add annotations to each line? How is the calling and looping process? Please tell me. As for CALL goto :eof, I can't understand this thing. Can you explain the call goto :eof? Thank you!

The call can invoke some external commands and internal commands, and can also invoke the label segments within the batch processing program. Here, call :print means invoking the :print program segment below this batch processing program. In addition, the call can also call the batch program segment with parameters.
goto :eof means jumping out of this label if it is inside a label, and if it is in other positions of the batch processing program, it means jumping to the end of the batch processing program, that is, exiting the batch program.

With LZ's strength, he can definitely make another similar delay variable .bat. Eagerly looking forward to it.

In the batch command `echo\&pause&cls&echo.`, the backslash (`\`) here is just a literal character. In the context of a batch file, it doesn't have a special syntactic meaning like in some other programming languages. It's probably just part of the text that's being output or manipulated as part of the command sequence. So it's essentially just a character included in the string that the commands are dealing with.

Wow, so powerful, really strong. Then it jumps back later, the loop is really well done.

echo %%var:~%1,%2%% The characters after interception are: !var:~%1,%2!

Thank you~

Re tianlijian:
The symbols such as / and ; , . \ here have the same function, indicating to output an empty line.
Re star8289:
You can analyze its function in combination with the output of the code, where %1 and %2 represent the first and second command line parameters.

Can we make all batch commands into this kind of batch code with a demonstration function. But this is something that only experts can do. I hope someone interested will do this meaningful thing
