goto

GOTO

Direct a batch program to jump to a labelled line.

Syntax
      GOTO label 
Key
label : a predefined label in the batch program. Each label must be on a line by itself, beginning with a colon.

To exit a batch script file or exit a subroutine specify GOTO:eof this will transfer control to the end of the current batch file, or the end of the current subroutine.

Examples:

IF %1==12 GOTO MySubroutine
Echo the input was NOT 12
goto:eof

:MySubroutine
Echo the input was 12
goto:eof

Use a variable as a label

CHOICE /C:01 /m choose [Y]yes or [N]No
goto s_routine_%ERRORLEVEL%

:s_routine_0
Echo You typed Y for yes
goto:eof

:s_routine_1
Echo You typed N for no
goto:eof

Skip commands by using a variable as a :: comment (REM)

In this example the COPY command will only run if the parameter "Update" is supplied to the batch

@echo off
setlocal
IF /I NOT %1==Update SET _skip=::

%_skip% COPY x:\update.dat
%_skip% echo Update applied
...

If Command Extensions are disabled GOTO will no longer recognise the :EOF label
