    % using HB_DEFAULT() instead of DEFAULT TO and local DEFAULT() macro
      (it means that in these places, type checking is more thourough
      than before). I left DEFAULT TO in places where the default expression
      is complex.
    ! fixed TCODE():New() to not use Alert(), use ::DrawError() instead
    % HGetValue(): use HB_HGETDEF() instead of equivalent local logic
    % use HB_ISHASH() instead of ValType()
    % use hb_ntos() instead of LTrim( Str() )
    ; build tested only, pls review
