Welcome to the IBM COBOL Café. Here you will find the latest technical and business information, and educational information about COBOL and related z/OS, IBM i and AIX COBOL topics, including IBM Automatic Binary Optimizer for z/OS and IBM Developer for z Systems Enterprise Edition.
Attending Innovate ? Want to learn about, and gain experience with, the recently announced Enterprise COBOL for z/OS, V5.1 ? Enroll in hands-on technical workshop WKS-2280. The workshop will offer an overview of the new Enterprise COBOL for z/OS V5.1 compiler. The format of the workshop will be a combination of lecture, demonstration and hands-on exercises. As a participant in the workshop you will have the opportunity to use Rational Developer for z to complete the hands-on portion of the workshop. Some of the... [More]
If you're looking for more information about Enterprise COBOL for z/OS, V5.1 then you'll have several opportunities at IBM's Innovate 2014 conference, June 1 through 5. On Monday, June 2, from 12:30 to 1:15 in session 2481 - "How Compilers Reduce Operating Costs for Running Business Critical Applications on System z" is a Birds of a Feather session where you will be able to chat with us about the Enterprise COBOL for z/OS, Enterprise PL/I for z/OS, and z/OS XL C/C++ compilers. On Tuesday, June 3, from 12:30 to 1:30,... [More]
IBM Automatic Binary Optimizer for z/OS V1.1 is now available. IBM Automatic Binary Optimizer for z/OS is a product to improve the performance of already compiled IBM COBOL programs. The optimizer does not require source code, source code migration, or performance options tuning. It uses modern optimization technology to target the latest z Systems platforms, including z13, zEC12, and zBC12, to accelerate the performance of existing compiled COBOL applications. The input to IBM Automatic Binary Optimizer for z/OS... [More]
In COBOL for z/OS, V5,1, when compiling your source files that are too complex or in a relatively large size, and if you have specified the OPTIMIZE level, it may take excessive amount of time or storage. Thus a new compiler option, MAXPCF , is introduced to allow you to control the amount of time and storage used when optimizing a program. You can specify the maximum program complexity factor with this option. The new term, Program Complexity Factor (PCF), is a value calculated by the compiler, and represents the complexity of the program... [More]
Extended source format is introduced in COBOL for AIX, V4.1. The new extended source format is divided into distinct areas as before, but permits lines varying in length from a minimum of 0 bytes to a maximum of 252 bytes. The following figures illustrate the key difference between the two formats: Fixed source format: Extended source format: For both formats, lines shorter than the maximum length are logically extended with space to the maximum length. You can use the SRCFORMAT option to indicate whether your COBOL source... [More]
This is the first in a series of blog entries that I'll be creating on the subject of debugging IBM Enterprise COBOL for z/OS V5.1 using Debug Tool. In particular, I'll be pointing out some of the improvements you'll see compared to debugging earlier versions of Enterprise COBOL. The first improvement has to do with Level 88 Condition Names. With previous versions of Enterprise COBOL, the LIST command will show you the value of the Level 88 Condition Name (TRUE or FALSE), but not the value of variable with which the Condition Name...

This is the third 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 entry is regarding Debug Tool's behaviour when stepping over an out-of-line PERFORM . An out-of-line PERFORM is like a procedure call that entails a branch to a named paragraph and an implicit return from that paragraph. This is somewhat similar to calling a sub-program using the CALL... [More]

In particular, I'll be pointing out some of the improvements you'll see compared to debugging earlier versions of Enterprise COBOL. This entry is regarding Debug Tool's AUTOMONITOR feature. Specifically, it is about how AUTOMONITOR handles statements that use the LENGTH OF or ADDRESS OF special registers. I'll use this simple example program to illustrate the differences... [More]
