------------------------------------------------------------------------------
 Syntax

     <object>:<message>[(<argument list>)]

 Type

     Object

 Operands

     <object> is the name of the object that is to receive the message.

     <message> is the name of a method or instance variable.

     <argument list> is a list of parameters that are passed to the
     specified message.  The parentheses surrounding the argument list are
     optional if no parameters are supplied in the message send.  By
     convention, however, parentheses distinguish a message send with no
     parameters from an access to an exported instance variable.

 Description

     Each class defines a set of operations that can be performed on objects
     of that class.  Perform these operations by sending a message to the
     object using the send operator (:).

     When a message is sent to an object, the system examines the message.
     If the object is of a class that defines an operation for that message,
     the system automatically invokes a method to perform the operation on
     the specified object.  If the class does not define a method for the
     specified message, a runtime error occurs.

     Executing a message send produces a return value, much like a function
     call.  The return value varies depending on the operation performed.

 Examples

     .  In this example, myBrowse is the name of a variable that
        contains a TBrowse object reference.  pageUp() is a method that
        specifies the operation to be performed.  The available operations
        and corresponding methods vary depending on the class of the object.
        The Error, Get, TBColumn, and TBrowse classes are documented in this
        chapter.

        myBrowse:pageUp()

     .  This example forces the checkbox state to true (.T.):

        myCheck : Select (.T.)
