In June, IBM COBOL for AIX, V5.1 and IBM COBOL Runtime Environment for AIX, V5.1 GAed. A key difference from previous versions of COBOL for AIX is that, V5.1 delivers improved runtime performance and functionality. Specifically, with COBOL for AIX, V5.1, the runtime library components cannot be redistributed with developed applications. This runtime can only be used in a development environment, on the same machine as the COBOL for AIX compiler. Deployment of COBOL applications in an execution only environment will require the new IBM COBOL... [More]

In COBOL, one may write invalid programs or use invalid data in program which can be compiled and executed but lead to technically incorrect or even unexpected results. It's the responsibility of the COBOL programmer to make sure that programs and data are valid, and as the behavior of invalid programs (or programs with invalid data) is undefined, IBM makes no guarantees that the result in these cases won't change between compiler releases or even PTFs. While migrating from Enterprise COBOL V4.2 to Enterprise COBOL V5, some users... [More]

Enterprise COBOL for z/OS V5.2 provides day 1 support for the new z processor. Besides the ability to generate new z13 instructions, this new compiler also has abilities to use the new Vector Facility for certain COBOL statements, and expand usage of Decimal Floating Point Facility for Packed Decimal calculations. Enterprise COBOL V5.2 provides significant performance improvements over the GA release of Enterprise COBOL V5.1. Well-structured, compute intensive batch applications running on z13 (compiled with Enterprise COBOL V5.2) have shown... [More]
This is the sixth in a series of blog entries on the subject of debugging IBM Enterprise COBOL for z/OS V5.1 using Debug Tool. These blog entries point out some of the improvements you'll see compared to debugging earlier versions of Enterprise COBOL. This blog entry is regarding Debug Tool's support for COBOL data types. With previous versions of COBOL there were several restrictions on which data types were supported in the various Debug Tool commands. In particular, commands which perform assignment, such as MOVE, and commands which... [More]
Enterprise COBOL V5 provides increased exploitation of the latest z/Architecture processors, as well as new levels of optimization, to improve the performance of z/OS COBOL applications. To that effect, several new compiler options are introduced in V5, including AFP, ARCH, HGPR, OPTIMIZE, and STGOPT. Some were mentioned in previous blogs and now we want to bring the HGPR option in. The HGPR option controls the compiler usage of the 64-bit registers provided by z/Architecture processors, and its syntax is as follows:... [More]
