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.

For example:

IF %1==12 GOTO s_december
:: other commands
:s_december

GOTO :eof

An easy way to exit a batch script file without defining a label is to specify
GOTO :eof
this transfers control to the end of the current batch file.

Using a variable as a label

CHOICE
goto s_routine_%ERRORLEVEL%

:s_routine_0
echo You typed Y for yes

:s_routine_1
echo You typed N for no

Skipping commands by using a variable as an optional :: (REM) comment

In this example the 2 COPY commands will only run if the parameter "Update_Now" is supplied to the batch

@echo off
setlocal
IF [%1]==[] GOTO :eof
IF /I NOT %1==Update_Now SET v_skip=::

%v_skip% COPY x:\update.dat
echo Your WWW connection is up to date

%v_skip% COPY x:\FTP.dat
echo Your FTP connection is up to date
