Hm ... Do you have some link(s) to cmd.exe shell documentations ? (even advanced !) José.

exit n from perl will return a status to the cmd.exe shell, and you can test for this value with if errorlevel n in the batch file. Hence, given ErrLevel.pl: #!perl print "ARGV[0] = $ARGV[0]\n"; exit $ARGV[0]; and ErrLevel.cmd: perl -w ErrLevel.pl %1% if ERRORLEVEL 2 echo ErrorLevel 2 if ERRORLEVEL 1 echo ErrorLevel 1 echo end of script Running "ErrLevel 1" gives output: ARGV[0] = 1 ErrorLevel 1 end of script Note, if errorlevel n checks for return code >= n, hence "ErrLevel 2" gives: ARGV[0] = 1 ErrorLevel 1 ErrorLevel 2 end of script Thus usually, the script uses if errorlevel n goto label to branch away and another label after the if's for the return goto to target.
