ECO KIT SUMMARY:

An ECO kit exists for the  DEC COBOL Run-Time Library on DEC OSF/1 V2.0
through V3.0. This kit addresses the following problems:


      o  If you declare the FILE STATUS variable within  a  record  such
         that its characters span two quadwords, the second character of
         the variable is not updated after the execution of an I-O verb.

      o  If your application contains any  extended  ACCEPT  or  DISPLAY
         statements  and your application displays escape sequences when
         the cursor is in the lower right corner of the screen, you  may
         see the screen scroll unexpectedly.

         In an attempt to correct this problem, this release of the  DEC
         COBOL Run Time Library no longer advances to the next line when
         the cursor is past the rightmost column of the screen  and  the
         src-item begins with an escape sequence.

      o  If your application performs an ACCEPT  WITH  CONVERSION  of  a
         JUSTIFIED    data    item,   the   resulting   value   is   not
         right-justified.

      o  When  your  application  mixes  OPEN  INPUT  and  OPEN   OUTPUT
         operations  on  multiple-reel,  multiple-file tapes without the
         use of the MULTIPLE FILE TAPE syntax, the potential  exists  to
         corrupt files.

         The sequence of events which cause this corruption to occur are
         as follows:

          -  your application performs an OPEN INPUT  of  a  file  which
             spans multiple reels

          -  when the current reel is not the last  reel,  the  file  is
             closed with NO REWIND

          -  the next operation on the tape drive is an OPEN  OUTPUT  NO
             REWIND

          -  a tape swap is performed, and the file is  created  at  the
             beginning  of  the  tape,  overwriting  the contents of the
             existing file

      o  If you open a non-indexed file in OUTPUT  mode,  the  resulting
         file access does not grant write access to group.

      o  Files open in INPUT mode no longer acquire a record lock during
         a  READ  operation no matter what ALLOWING clause is specified.
         This is consistent with  automatic  record  locking;  with  DEC
         Cobol and VAX Cobol behavior on OpenVMS; and with X/Open record
         locking concepts.

         Related to the above item, for INDEXED files, ALLOWING  READERS
         has  always  been  unsupported  on this platform and was always
         treated as "NO OTHERS".  Now it is downgraded to "ALLOWING ALL"
         if the file is opened in INPUT mode.

      o  READ operations for INDEXED files do not detect a locked record
         when a lock is not requested (ALLOWING ALL or WITH NO LOCK).  A
         hard lock condition only occurs if a lock  is  requested  (e.g.
         ALLOWING  NO  OTHERS,  WITH LOCK, automatic).  Detecting a lock
         should not be dependent on requesting a lock.
