o:cToChar( <cCtrlClass> ) -> <cStructure>
------------------------------------------------------------------------------

 PARAMETER:

  <cCtrlClass> is the API classname of the control that will be 
               included in the structure built by ::cToChar()


 RETURNS:

  <cStructure>  is the control structure. This structure is stored as a
                character string because Clipper has no provisions for making 
                and using structures.


 DESCRIPTION:

  The ::cToChar() method creates a string with the structure that is 
  needed by the Windows API functions to create a window.
  The information is stored in a string because Clipper unfortunately has no 
  knowledge of structure's since this is not a part of the Clipper language.
