RSD filesystem change when migrating an exe and data file from COBOL for AIX, V3.1 to V5.1
Scenario: A data file contains dates listed repeatedly many times in a horizontal line entry with the YYYYMMDD format. An exe reads from that data file when compiled with V3.1. But however, after compiling with V5.1. the exe produces the trace below. However, if the dates in the data file are re-arranged one by one vertically (ie one date per line), the exe runs successfully when compiled with V5.1. Why is this the case? Traceback: <Thread 1> <Thread 1> Traceback: <Thread 1> Offset 0x00000694 in procedure... [More]

IBM Automatic Binary Optimizer for z/OS now supports modules compiled with the CMPR2 option
Starting with the IBM Automatic Binary Optimizer for z/OS (ABO) V1.3 continuous delivery PTF, released Jan 27, 2019 , you can now use ABO to optimize modules built with the CMPR2 compiler option. The CMPR2 compiler option was available in COBOL compilers VS COBOL II V3 up to COBOL for OS/390® V2 and allowed COBOL code conforming to the 74 COBOL standard to be successfully compiled. Enterprise COBOL does not support this option and requires that code is migrated to the 85 COBOL standard. Clients with programs compiled with the CMPR2 option... [More]
