MESSAGE...METHOD
 Declare message and corresponding method
------------------------------------------------------------------------------

 Syntax:

    MESSAGE <message name> METHOD <method name> [CONSTRUCTOR | CTOR]

 Arguments:

    <message name> is the name of the message being declared.  Like a
    Clipper variable, up to 10 characters are significant.  Extra characters
    will be ignored.

    <method name> is the name of the method to invoke when the specified
    message is sent.  A method of this name should be defined later in the
    same module using the METHOD PROCEDURE or METHOD FUNCTION command,
    unless an external method is being declared.

 Description:

    This command allows a method to be declared which is invoked by a
    message with a name different from that of the method.  This may be
    necessary for one of several reasons:

    1.  The message name conflicts with a reserved Nantucket name. Examples
        of this are left, right, and at. These are functions
        which the Clipper compiler handles specially, so having methods
        with the same names is problematic.  However, this does not prevent
        the use of the same message name.  To map a message to a method
        with a different name, you would use a statement such as the
        following:

            MESSAGE left METHOD boxLeft

        In this example, the message left is mapped to the method called
        boxLeft.

    2.  When an ordinary function is called which has the same name as the
        method from which it is being called.  For example, attempting to
        call a function called display from a method called display will
        result in an endless recursive loop.  To resolve this, give the
        method a different name, for example:

            MESSAGE display METHOD boxDisplay

        This maps the message display to a method called boxDisplay. Now if
        a UDF called Display() is called from within the boxDisplay method,
        everything works as expected.

    3.  To map a message to a method which for some reason must be defined
        in a module other than the one containing the class declaration.
        This is not usually recommended practice, but it can be done.  See
        the section entitled External Methods.

    4.  To map two or more messages in a class to the same method. This
        might be required to support an obsolete message which is still in
        use.  For example:

            MESSAGE getValue METHOD get
            METHOD  get

        In this case, the messages getValue and get both map to the
        same method, named get.  Note that the second statement above
        uses the default behaviour of the METHOD command to name a message
        and method the same name - it would be unnecessary (although it
        would work) to use MESSAGE get METHOD get.

 Note:

    If the optional CONSTRUCTOR clause is included (or its abbreviation
    CTOR), then the method and its associated message are flagged as a
    constructor method and message respectively. See Constructor Messages
    and Methods for more information.
