METHOD MethodName( [ Param1 [, ParamN ] ] ) CONSTRUCTOR
METHOD MethodName( [ Par1 [, ParN ] ] ) BLOCK ;
{ | Self [, Par1 [, ParN ] ] | Actions, , , }
METHOD MethodName( [ Par1 [, ParN ] ] ) SETGET
METHOD MethodName( [ Par1 [, ParN ] ] ) VIRTUAL
METHOD MethodName( [ Par1 [, ParN ] ] )
ENDCLASS
METHOD DEFINITION
METHOD MethodName( Par1, Par2, ... ) CLASS ClassName
...
[ ::Parent:New( Par1, Par2, ... ) ]
...
::DataName1 := ...

::MethodName( ... )
...
Return [ Return Value ]
CLASS : Indicates the start of a class definition
FROM : Determines if the class must receive the methods and
instances from other class that will be superclass or
master class.
DATA : Allows define instances or internal variables from the
class.
METHOD : Allows define methods of the class.
CONSTRUCTOR : Indicates the constructor method of the class.
BLOCK : Allows define a method like a codeblock.
VIRTUAL : Allows define empty methods.
ENDCLASS : Marks the end of the definition of the class.
Description:
Allows define new classes in Clipper. You must access to the non-
documented functions of the SEND module.
The Methods and Instances of the new class will be all defined in
the moment of creation anyway all that they have the superclass
from wich receive the current in case that a FROM sentence has
been defined
Return:
Not available.
Example:
Function oDemo()
Local oPrueba := TDemo():New( 33, 10 )
oPrueba:cMess := "Welcome to Fast Library"
oPrueba:SetClr := "W/B"
oPrueba:Message()
Return ( Nil )
CLASS TDemo
DATA nPosX
DATA nPosY
DATA cMens
DATA cClr
METHOD New( nY, nX ) CONSTRUCTOR
METHOD Message()
METHOD SetClr( cC ) BLOCK { | Self, cC | ::cClr := cC }
ENDCLASS
METHOD Function New( nY, nX )
::nPosY := nY
::nPosX := nX
Return( Self )
METHOD Function Mess()
@ ::nPosY, ::nPosX Say ::cMess Color ::cClr
Return( Self )
