Goto lets you take commands from the batch file beginning with

separators, such as semicolons or equal signs. If your batch file
does not contain the label, the batch file terminates. ( \

ignored during batch processing.
Example: ,
The following example sends the program processor to the label
named end only if no errors occur when you format the disk in
drive A: i \
:begin
echo off
format a: /s ivs j
if errorlevel 0 goto end
echo An error occurred during formatting.
:end
echo End of batch file.
