Comments
You can start a comment anywhere outside a string by typing a double hyphen (--). If the text
immediately after -- is anything other than double left brackets ([[), the comment is a short
comment, which continues until the end of the line.
If -- is followed by [[, the following characters are a long comment, which continues until double
right brackets (]]) close the comment. Long comments may continue for several lines and may
contain nested [[ . . . ]] pairs. The example below shows how to use code comments.
An example of a short comment is:
-- Turn off the front-panel display.
An example of a long comment is:
--[[Display a menu with three menu items. If the second menu item is selected,
the selection will be given the value Test2.]]
