Comments in PML Files

Comments are additional text included in a PML file for the benefit of someone reading the PML code.

The PML processor ignores comments and so they do not affect the way the code executes.

For a simple one-line comment, begin the line with - - (two dashes) or $* (dollar and asterisk).

- - This is a new-style PML comment

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

$* The following lines calculate the new angle

You can also use $* to add an inline comment to any line of PML:

A comment may extend over several lines provided it is enclosed in the escape sequences $( and $).

$( A comment containing

more than one line $)

A comment of this kind can be used temporarily to comment-out lines of PML to prevent them from being executed, but without deleting them from the file:

$(

 skip if (!X EQ !Y)

$)
