         state) after an upgrade to Motif V1.2-5.

          -  [SYSLIB]DEBUGSHR.EXE

          -  [SYSLIB]VMSDEBUGUIL.UID




Problems addressed in ALPDEBU03_071 kit


      o  Examines  (checks)  of  global/shared  data  often  show  stale
         values.

      o  Monitor view performance suffers severe performance degradation
         when  the  number  of  monitored items increases.  For example,
         expanding a 900-element  aggregate  could  take  more  than  20
         minutes.   The  performance  loss continues even when monitored
         items are collapsed or removed (even across runs/reruns).   The
         performance degradation first started in OpenVMS V7.0.

         After installation of this kit the same  expansion  would  take
         under a minute.

      o  Links for System Code  Debugger  (SCD)  relevant  OpenVMS  V6.2
         debug  image  versions  failed  to  deassign  a  SYS$BASE_IMAGE
         logical.

         The original linktime problem occurred with DEBUG.EXE, since it
         was  linked  against an OpenVMS V6.2 version of SYS$BASE_IMAGE.
         In this case, some features such as SET  BREAK/SYSEMULATE  were
         disabled.



Problems addressed in ALPDEBU02_071 kit


      o  The debugger sometimes displays the wrong source  and  symbolic
         information.   That  is,  sometimes  it reads the DSTs from the
         wrong image or DSF file.

      o  Some commands, with several different languages, yield messages
         similar to:

         %DEBUG-E-OPNOTALLOW, operator 'AND' not allowed on  given  data
         types


                                                                Page 3


Problems addressed in ALPDEBU01_071 kit


      o  Build the debugger against Motif V1.2-3 and provide workarounds
         in  the  debugger  for  bugs which are currently fixed in Motif
         V1.2-4.
