Comments and Compiler Directives Comments are ignored by the compiler, except when they function as separators (delimiting adjacent tokens) or
compiler directives.
There are several ways to construct comments:
{ Text between a left brace and a right brace constitutes a comment. }
(* Text between a left-parenthesis-plus-asterisk and an asterisk-plus-right-
parenthesis is also a comment *)
// Any text between a double-slash and the end of the line constitutes a comment.
Comments that are alike cannot be nested. For instance,
{{}}
will not work, but
(*{}*)
will. This is useful for
commenting out sections of code that also contain comments.
A comment that contains a dollar sign ($) immediately after the opening { or (* is a compiler directive. For example,
{$WARNINGS OFF}
tells the compiler not to generate warning messages.
