** CVS/RCS Log:
** $Log: dcvrst.cc,v $
** Revision 1.14  2004/01/16 13:47:37  joergr
** Removed acknowledgements with e-mail addresses from CVS log.
** Added missing #include "osconfig.h".
**
** Revision 1.13  2002/12/06 13:05:52  joergr
** Fixed bug in Unlimited Text (UT) class: the backslash character was treated
** as a component separator which is wrong according to the DICOM standard.
** The same bug was found in class Long Text (LT) and Short Text (ST).  Also
** changed the behaviour of the getVM() method; now returns 1 only in case of
** non-empty string values.
** Made source code formatting more consistent with other modules/files.
**
** Revision 1.12  2002/04/25 10:33:40  joergr
** Added/modified getOFStringArray() implementation.
**
** Revision 1.11  2001/09/25 17:20:01  meichel
** Adapted dcmdata to class OFCondition
**
** Revision 1.10  2001/06/01 15:49:20  meichel
** Updated copyright header
**
** Revision 1.9  2000/03/08 16:26:51  meichel
** Updated copyright header.
**
** Revision 1.8  1999/03/31 09:25:59  meichel
** Updated copyright header in module dcmdata
**
** Revision 1.7  1998/11/12 16:48:29  meichel
** Implemented operator= for all classes derived from DcmObject.
**
** Revision 1.6  1997/08/29 13:11:49  andreas
** Corrected Bug in getOFStringArray Implementation
**
** Revision 1.5  1997/08/29 08:33:01  andreas
** - Added methods getOFString and getOFStringArray for all
**   string VRs. These methods are able to normalise the value, i. e.
**   to remove leading and trailing spaces. This will be done only if
**   it is described in the standard that these spaces are not relevant.
**   These methods do not test the strings for conformance, this means
**   especially that they do not delete spaces where they are not allowed!
**   getOFStringArray returns the string with all its parts separated by \
**   and getOFString returns only one value of the string.
**   CAUTION: Currently getString returns a string with trailing
**   spaces removed (if dcmEnableAutomaticInputDataCorrection == OFTrue) and
**   truncates the original string (since it is not copied!). If you rely on this
**   behaviour please change your application now.
**   Future changes will ensure that getString returns the original
**   string from the DICOM object (NULL terminated) inclusive padding.
**   Currently, if you call getOF... before calling getString without
**   normalisation, you can get the original string read from the DICOM object.
**
** Revision 1.4  1997/07/03 15:10:19  andreas
** - removed debugging functions Bdebug() and Edebug() since
**   they write a static array and are not very useful at all.
**   Cdebug and Vdebug are merged since they have the same semantics.
**   The debugging functions in dcmdata changed their interfaces
**   (see dcmdata/include/dcdebug.h)
**
** Revision 1.3  1996/01/05 13:27:54  andreas
** - changed to support new streaming facilities
** - unique read/write methods for file and block transfer
** - more cleanups
**
