30rem Note! We're using %ERRORLEVEL% here instead of the classic
31rem IF ERRORLEVEL 0 GOTO blah because the latter cannot handle
32rem the complete range or status codes while the former can.
33rem
34rem Note! SET changes ERRORLEVEL on XP+, so we have to ECHO
35rem before incrementing the counter.
