Description
Comment delimiter; indicates the beginning of a script comment. Any characters that appear
between the comment delimiter (//) and the end-of-line character are interpreted as a
comment and ignored by the ActionScript interpreter.
Example
The following example uses comment delimiters to identify the first, third, fifth, and seventh
lines as comments:
// Record the X position of the ball movie clip.
ballX = ball._x;
// Record the
Y position of the ball movie clip.
ballY = ball._y;
// Record the
X position of the bat movie clip.
batX = bat._x;
// Record the
Y position of the bat movie clip.
batY = bat._y;
