Not sure why you would need to do this.

Code: Select all

set label=:top

:top
set /a num+=1
echo %num%
goto %label%

as FOR /L hangs with big numbers goto loop sometimes is the only way to use iteration loops: http://www.dostips.com/forum/viewtopic.php?t=3487

though it should be used rarely as it hits the performance.

The simplest example of a similar code is this:

Code: Select all

choice /C ABC /M "Enter desired option: "
goto option-%errorlevel%

:option-1  A


:option-2  B

etc...

goto as variable already used as following:

This allows you to invert the sequence between programming sets

Code: Select all

@echo off
set exitprogram1=program3
set exitprogram3=program2
set exitprogram2=completed
goto program1
rem -------------------------------1
:program1
echo.1
goto %exitprogram1%
rem -------------------------------2
:program2
echo.2
goto %exitprogram2%
rem -------------------------------3
:program3
echo.3
goto %exitprogram3%
:completed
pause
