Inheriting from Clipper's Classes

  Clipper's classes can be used as though they were Class(y) classes. This
  means they can be inherited from, for example:

    CREATE CLASS BetterBrowse FROM TBrowse
       .
       .

  Also, the Class(y) instantiation syntax can (optionally) be used instead
  of Clipper's. Four class functions have been provided for this purpose:
  TBrowse(), TBColumn(), Get(), and Error(). For example:

    oBr := TBrowseNew(5, 5, 15, 70)

  becomes:

    oBr := TBrowse():new(5, 5, 15, 70)

  This allows greater consistency. Either or both syntaxes can be used in
  the same program.
