#CommentFlag

Changes the script's comment symbol from semicolon to some other string.

Note: This directive is not recommended for use in new scripts because a) it does more harm than good and b) it is no longer available in AutoHotkey v2.

#CommentFlag NewString

Parameters

NewString

One or more characters that should be used as the new comment flag. Up to 15 characters may be specified.

Remarks

The default comment flag is semicolon (;).

The comment flag is used to indicate that text that follows it should not be acted upon by the script (comments are not loaded into memory when a script is launched, so they do not affect performance).

A comment flag that appears on the same line as a command is not considered to mark a comment unless it has at least one space or tab to its left. For example:

MsgBox, Test1 ; This is a comment.
MsgBox, Test2; This is not a comment and will be displayed by MsgBox.
