Comments can be inserted in scripts.

They are ignored by the language and help provide information on the intent of the script or statement.

% is used for commenting: anything following the % sign on the line is disregarded.

A = 2 + 2 % comment here

A comment can be an entire line as well.

%This line does nothing.

%{ %} is a comment block. Any text within the block is ignored, like a normal comment. This is use for comments that take up multiple lines.

%{  This is
a comment
of more than one
line %}
