Comments

A comment is a piece of text that is ignored by the compiler. Comments may serve as extra documentation, or to temporarily disable a part of the code.

Line comments start with // and end with the end of the line. For example:

// End of script
terminate_this_script

Or:

terminate_this_script // End of script

There are two ways to write block comments. The first is using curly braces { and }:

wait {comments here} 0

The second is using /* and */, similar to C++. They can span multiple lines:

/*
 This is a multi-line comment.
 It spans multiple lines.
*/

Or used in the middle of the code:

set_time_of_day /* hours */ 12 /* minutes */ 30

Note

{} comments may look similar to directives like {$CLEO .cs} which we will learn about next. The difference is that directives always start with {$. Everything else inside {} is treated as a comment.

Block comments can not be nested. For example, the following code is invalid:

/* This is a comment /* This is a nested comment */ */
