COMMENT
It is often helpful to use comments to include in the source
statements a description of certain FDL commands and their
functions. These comments are useful when debugging your
program and can act as reminders if you or someone else
modifies the .FSL later. When you use comments, they appear
on the source statement only. They are not printed on your
form, and do not affect the execution of your program.

Comment nesting
/* begins a comment and */ ends a comment.
/* THIS IS THE START OF A NESTED COMMENT
/* WHEN TWO ENDING COMBINATIONS ARE FOUND */
THE COMMENT IS TERMINATED */

A syntax error results if /* does not begin a comment and */
does not end a comment. Each comment beginning (/*) and
ending (*/) should be followed by at least one space character.
does not end a comment. Each comment beginning (/*) and
ending (*/) should be followed by at least one space character.
Considerations
A semicolon must be inserted at the end of the comment text;
otherwise all of the following FDL commands are considered part
of the comment text and are not executed. The FDL compiler
ignores all comments up to the first encountered semicolon.
