China DOS Union

if errorlevel 5
means “if it is greater than or equal to 5”;
if not errorlevel 6
means “if it is less than 6”;

Then
if errorlevel 5 and if not errorlevel 6
means “equal to 5”

That understanding isn’t wrong, right!

But is a form like “if errorlevel 5 and if not errorlevel 6” correct? Does DOS recognize syntax like this?

Could an expert please point it out!

Thanks ：）

Actually, you’ve already more or less found the right answer; you just need to remove the and.

Thanks
