ECO KIT SUMMARY:

An ECO kit exists for DEC C++ Class Run Time Libraries on OpenVMS Alpha
V6.1 through V6.1-1H2.  This kit addresses the following problems: 

   o  An access violation or segmentation fault is no longer
      generated when your application writes into an uninitialized
      ostream_withassign.  Instead the written text is simply
      ignored.

   o  An access violation no longer occurs when a null pointer is
      passed to the insertion (<<) operator within the ostream
      class.

   o  A file positioning problem for bidirectional fstreams has been
      corrected.  Previously if your application switched from
      reading an fstream to writing an fstream, with or without an
      intervening seek operation, the necessary synchronization of
      the external file position with the get pointer was often
      skipped.  This resulted in the written data being placed
      incorrectly within the file.

   o  The real() function within the stopwatch class was incorrectly
      returning the CPU time.  Now it returns the clock time as
      documented.

   o  The >> operator within the istrstream class now works
      correctly when the conversion base format is hex and
      hexadecimal values are read which begin with "0" but 
      are not prefixed with "0x".

   o  The flush() function within the ostream class was incorrectly
      calling overflow().  Now flush() calls sync() as documented.

   o  The ignore() function within the istream class now works
      correctly.  Previously it would ignore two and only two
      characters. 

   o  The input functions within the stdiostream class no longer 
      skip every other character.

   o  The sync_with_stdio() function within the ios class no longer 
      causes subsequent istream operations to skip every other 
      character.  

   o  The SYS$OUTPUT and SYS$ERROR files are no longer opened during
      the initialization of cout and cerr, respectively.  Previously 
      this behavior resulted in an empty file being created when
      SYS$OUTPUT or SYS$ERROR was defined to be a file and the
      application generated no output.

   o  The showpoint flag within the ios class now forces the decimal
      point to be displayed.


INSTALLATION NOTES:                        

The system does not need to be rebooted after this kit is installed.

However, if you have other nodes in your VMScluster, they should be
rebooted or you should install this kit on each system in order to make
use of the new image(s).
