Yes, in this case this is not really an error.
But I remember other situations where it can be enterpreted as an error.
e.g. Download failure etc.
I don't want to blame Microsoft for the variable name "ERRORLEVEL" cause
it is rather historical, but it is the only way to catch a program's 
exit code in a batch.
