Windows batch comment out line

RobKennedy as I read the answer, it does not read anything after the ::, where everything after REM is read. If the command interpreter stops reading , James, then it would never execute any more of the file. It obviously needs to continue reading to discover where the comment ends and where next line of the file begins.

You can use :: or rem for comments. An example is shown here Only if comments are in if , use rem , as the colons could make errors, because they are a label.
