Comments / Remarks

:: This is a REMark

A colon (:), which is actually the LABEL tag, can be used for comments instead of REM, by doubling it (::), except within parentheses (i.e. except within a FOR loop).

Using a double-label within a loop can cause the batch script to fail, but ONLY if:

• The double-label is followed by a second double-label on the next line
• The double-label is followed by an empty line on the next line
• The double-label is the last line in the loop

In other words: if used within a loop, the double-label must be followed by a line which contains normal (i.e. valid) syntax. Even a single-label is valid syntax.

This error never occurs if the double-label is replaced with REM.

The error arising from a double-label occurs because CMD.EXE interprets :: as a drive letter (like C:).
