** Revision 1.9  1997/07/21 08:00:45  andreas
** - Corrected error in DcmDirectoryRecord::write since this routine can

**   characters).
** - Replace all boolean types (BOOLEAN, CTNBOOLEAN, DICOM_BOOL, BOOL)
**   with one unique boolean type OFBool.
**
** Revision 1.8  1997/07/07 07:42:04  andreas

**   element and sequence write functions changed.
**
** Revision 1.6  1997/05/09 13:12:02  hewett
** Added a member variable and associated get/set methods to DcmDirectoryRecord
** to allow the origin of a directory record to be noted.
**
** Revision 1.5  1997/05/06 09:22:35  hewett
** Added a "before" flag to the insertion of items for compatibility with
** insertion in normal Sequences.
**
** Revision 1.4  1997/03/26 16:56:25  hewett
** Removed the DcmDirectoryRecord member function fillTypeElements since it
** did nothing useful.  Smoothed out some poor indentation.
**
** Revision 1.3  1996/08/05 08:45:20  andreas
** new print routine with additional parameters:
**         - print into files
**         - fix output length for elements
** corrected error in search routine with parameter ESM_fromStackTop
**
** Revision 1.2  1996/01/05 13:22:54  andreas
