Syntax of a method call

To call a method belonging to an imported class, use the same syntax that you would use in Java. However, in addition, you must also enclose a method call in dollar signs ($), just as you would a variable. Examples:
$new FileInputStream('myFileName')$
An immediate string value (such as 'Elm Street', or 'myFileName' in the first example above) passed as a parameter to a method must be enclosed in single quotes, as usual (see In the advanced macro format, rules for representation of strings, etc.).
