OpenVMS__COBOL COBOLAE1025 and COBOLRTLAE1025 DEC COBOL V2.5 ECO Summary

TITLE: OpenVMS__COBOL COBOLAE1025 and COBOLRTLAE1025 DEC COBOL V2.5 ECO Summary Modification Date: 30-JUN-98 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. Copyright (c) Digital Equipment Corporation 1998. All rights reserved. PRODUCT: DIGITAL COBOL V2.5 for OpenVMS Alpha OP/SYS: DIGITAL OpenVMS Alpha COMPONENT: COBOLAE1025 COBOL$MSG.EXE COBOL.EXE REFORMAT.EXE COBOLRTLAE1025 DEC$COBRTL.EXE LIBOTS2.EXE SOURCE: Digital Equipment Corporation ECO INFORMATION: ECO Kit Name: COBOLAE1025 ECO Kits Superseded by This ECO Kit: None ECO Kit Approximate Size: 17,829 Blocks Saveset A - 288 Blocks Saveset B - 13,068 Blocks Cover Letter - 11 Blocks RTL Saveset A - 4,473 Blocks Kit Applies To: DEC COBOL Version 2.5 for OpenVMS Alpha OpenVMS Alpha V6.1, V6.1-1H1, V6.1-1H2, V6.2, V6.2-1H1, V6.2-1H2, V6.2-1H3, V7.0, V7.1, V7.1-1H1 System/Cluster Reboot Necessary: No Installation Rating: Information Not Available NOTE: In order to receive the full fixes listed in this kit, the following remedial kits also need to be installed: None 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 installed.
