Modification Type:  New Kit

NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for DEC COBOL V2.5 on OpenVMS Alpha V6.1 through 
V7.1-1H1.

This release includes an updated compiler and an updated RTL.

The DIGITAL COBOL Release Notes contain a complete explanation of this 
release.

Below is a brief description of problem fixes with V2.5-980 beyond V2.5-961 
SSB.

  o  V2.5-980  A problem has been corrected in the compiler's processing
               of the WHERE clause of the DBMS DML FETCH and FIND 
               statements for a non-database data-item of usage COMP-3.  
               The problem caused the length of the data-item to be 
               improperly truncated, which caused incorrect data to be 
               retrieved from the database.

  o  V2.5-980  An error in the compiler which could cause the wrong WHEN
               phrase to be selected has been fixed.  This problem could
               occur in an EVALUATE statement when either the subject item
               or the object item was a national variable (described by a
               PICTURE character-string containing the symbol N).

  o  V2.5-980  The compiler now includes /SWITCH=DC_STOP_STATUS
               which can be used to force the generated code to call
               SYS$EXIT using the identifier specified in PROCEDURE
               DIVISION GIVING when the COBOL program explicitly
               specifies that the run unit is to stop (such as when
               EXIT PROGRAM is used in a program compiled with
               /STANDARD=V3 and activated from DCL rather than from
               a subprogram call).  The compiler will issue a diagnostic
               if this switch is specified but not needed during
               compilation.  This diagnostic can be suppressed by
               compiling /SWITCH=(DC_STOP_STATUS,NO_UNUSED_SWIDMP).

               Note that this switch is temporary for this V2.5 bug
               fix kit.  The method of requesting stop with status
               on the command line will likely change with DIGITAL
               COBOL V2.6.

  o  V2.5-980  A problem has been corrected in the handling of COMPUTE
               statements that divide decimal or integer variables or
               expressions by powers of 10 expressed using the
               exponentiation operator("**").  By default floating-point
               arithmetic is used to evaluate exponentiation; this  gives
               approximate results which are often not suitable for
               applications dealing with fixed-point quantities.  If you
               compile with /MATH=CIT3, cobol intermediate arithmetic is
               used to evaluate exponentiation; in its current state of
               development, it provides exact results for  exponentiation
               raising 10 (or a power of 10) to an integer power and
               provides decimal arithmetic for raising fixed-point values
               to an integer power.

                If you compile with /MATH=CIT3, you also need the new RTL
                kit for any program which uses exponentiation.

  o  V2.5-980  A problem in the compiler has been corrected which could
               cause the wrong results when a COMPUTE statement involving
               decimal or integer operands had more than one binary
               arithmetic operator.

               This problem was introduced subsequent to the DIGITAL COBOL
               V2.5-961 SSB release.

  o  V2.5-980  [RTL] A problem has been corrected with the runtime 
               library concerning an internal consistency check 
               during a WRITE statement on an INDEXED file when 
               following START statements using an alternate key and 
               the relational operator ">".


INSTALLATION NOTES:

The system/cluster does not need to be rebooted after this kit is
