Error description
Specification exception 0C6 s0C6 occurring in module IGZBXXMU at offset x'27E'
Local fix
Run with June 2025 ptf level (UO03703)
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 5 and later * * releases running programs on z/OS 3.1 and * * 3.2 which perform long multiplication * * described in PH67050 after applying the * * affected PTF below. * * * * July 2025 COBOL Runtime PTF: * * V3R1:UO04169 / V3R2:UO04171 * **************************************************************** * PROBLEM DESCRIPTION: An AMODE 31 COBOL program abends with * * S0C6 at entry IGZXXMU0 in module * * IGZXLPKA. * * * * When a dump is taken, the instructions * * around the abending location are * * as follows: * * * * 5810 100C L ... * * E700 1000 0806 VL ... * * E710 2000 0806 VL ... * * E620 0009 0C5B VPSOP ... * * E631 0008 FC5B VPSOP ... * * E640 7008 FC59 VSRP ... * * E651 7108 FC59 VSRP ... * * E664 3009 EE78 VMP ... * **************************************************************** * RECOMMENDATION: Install the provided PTF. * **************************************************************** APAR PH67050 which was delivered in the July 2025 PTF, enhances long multiplication performance by exploiting the 'Vector Packed Decimal Enhancement Facility 1'. However, the COBOL Runtime does not verify the availability of the facility before using the enhanced long multiplication. As a result, a specification exception (S0C6) can occur during execution if the facility is not installed. This APAR officially marks the July 2025 COBOL Runtime AMODE 31 PTFs as "Program in error (PE)". The PE'd July PTFs include: V2R5: UO04166, UO04167(JPN) V3R1: UO04169, UO04170(JPN) V3R2: UO04171, UO04172(JPN) Note: Although the V2R5 PTFs are not directly affected by this issue, they have been PE'd for SMP/E packaging reasons. For more information, see: PH67050: NEW FUNC: LONG MULTIPLICATION PERFORMANCE IMPROVEMENT refer to https://www.ibm.com/support/pages/apar/PH67050 COB0501T/K COB0502T/K COB0601T/K COB0602T/K COB0603T/K COB0604T/K COB0605T/K
Problem conclusion
The changes for APAR PH67050 have been reverted in the COBOL Runtime.
