This question is too vague to be answerable

Code: Select all

@echo off
echo Script Name
call :MakeUnderscore 12
echo Hello World
pause
exit /b
::--------------------------
:MakeUnderscore
for /l %%i in (1,1,%1) do (
    set /p =-<nul
)
echo(
Exit /B
::--------------------------

The subroutine :MakeUnderscore uses a for loop to generate a series of underscores based on the number passed as an argument. set /p =-<nul command is used to print an underscore without a newline character.
The echo( command is then used to print a newline character.
Finally, the Exit /B command is used to exit the subroutine.
