INIT CLASS:
 Begin user-defined initialization of class
------------------------------------------------------------------------------

 Syntax:

    INIT [CLASS]:

 Description:

    This command is used within a class declaration block to allow
    initialization of class variables, and any other class initialization
    that is required, when a class is created.

    The command should appear after all other class declaration commands,
    but before the END CLASS command.  After the INIT CLASS: command,
    initialization can be performed as though a class method were being
    executed.  The self variable will contain a reference to the class
    object, allowing access to class variables and methods.  This facility
    can be thought of as a constructor for the class, as opposed to
    instances of the class.
