Limits visibility of member variables and methods to subclasses

Syntax
PROTECTED:
Description

The member variables and methods which are declared after PROTECTED: are only visible within the source code of the methods of the declared class and its subclasses and can only be used within these methods.

Examples
PROTECTED: implementation 
// The example illustrates how the visibility attribute 
// is defined with a class declaration. 

CLASS classA 
  VAR varA                          // Visibility is  HIDDEN: 

  EXPORTED: 
  VAR varB, varC                    // Globally visible 
  METHOD methodA, methodB 

  PROTECTED: 
  VAR varD, varE                    // Visible only in methods 
  METHOD methodC, methodD
