ECO INFORMATION:

     ECO Kit Name:  ALPDPML01_071
     ECO Kits Superseded by This ECO Kit:  None
     ECO Kit Approximate Size:  1721 Blocks
                    Saveset A - 1710 Blocks

     Kit Applies To:  OpenVMS Alpha V7.1 through V7.1-1H2
     System/Cluster Reboot Necessary:  Yes

     Installation Rating:   3 - To be installed on all systems running
                                the listed versions of OpenVMS which
                                are experiencing the problems described.


ECO KIT SUMMARY:

An ECO kit exists for DIGITAL Portable Math Library (DPML) on OpenVMS
Alpha V7.1 through V7.1-1H2.  This kit addresses the following problems:

  o  After upgrading from OpenVMS alpha V7.0 to V7.1, an application
     calling   a   DPML   (DPML$SHR.EXE)   routine   failed  with  a
     %SYSTEM-F_HPARITH error.

  o  The problem statement for this QAR  included  a  small  program
     which showed that

         pow ( 4.079442787314344e-16, 20.  )

     failed with compiled with -D-FASTMATH,  but  worked  otherwise.
     The  equivalent VMS scenario produces an HPARITH trap caused by
     using a denormal value as an operand.

  o  MATH$NXTAFTR_F and MATH$NXTAFTR_G were returning  an  incorrect
     value when an overflow condition occurred.


RELATED ARTICLES:

Detailed articles describing the problems listed above may exist in
the DPML database.  To view these articles, open the appropriate product
database and perform a query using either of the following search strings:

ECO KIT ORDERING INSTRUCTIONS:

If after an evaluation you wish to obtain this kit, request it
electronically using the appropriate Advanced Electronic Services
(AES) Service Tool.  If you are not familiar with how to request
kits electronically, open the DIA, WIS or DSNLINK database and
review the article entitled:

     [AES] How To Electronically Request ECO Kits Using Service Tools


INSTALLATION NOTES:

Install this kit with the VMSINSTAL utility  by  logging  into  the
SYSTEM account, and typing the following at the DCL prompt:

   @SYS$UPDATE:VMSINSTAL ALPDPML01_071 [location of the saveset]

The saveset location may be a tape drive, or a disk directory  that
contains the kit saveset.

System should be rebooted after successful installation of the kit.
If  you  have  other  nodes in your VMScluster, they should also be
rebooted in order to make use of the new image(s).
