20rem Note! We're using %ERRORLEVEL% here instead of the classic
21rem IF ERRORLEVEL 0 GOTO blah because the latter cannot handle
22rem the complete range or status codes while the former can.
23rem
24rem Note! SET changes ERRORLEVEL on XP+, so we have to ECHO
25rem before incrementing the counter.
