Question: when WBAT commands go beyond 9 lines, how should I write it if I want to add more commands?
if errorlevel 9 goto 0009
if errorlevel 8 goto 0008
if errorlevel 7 goto 0007
if errorlevel 6 goto 0006
if errorlevel 5 goto 0005
if errorlevel 4 goto 0004
if errorlevel 3 goto 0003
if errorlevel 2 goto 0002
if errorlevel 1 goto 0001
