Though it has been half century that COBOL has been around, it is still the most dominant language for running business-critical applications, and it is the backbone for organizations everywhere. Among them, a majority of the business transactions processed by COBOL run on IBM System z hardware. Given this , IBM is making a latest refresh to this venerable language on z/OS, the V5.1 release will go alive on June 21! Generally speaking, IBM says the Enterprise COBOL for z/OS, V5.1 compiler will give applications a 15-20 percent... [More]
To define variable length tables in COBOL, we usually specify the OCCURS ... DEPENDING ON clause in the data description entry for an item contained within a group structure. While this defines an item with a variable number of occurrences at run time, in earlier versions before Enterprise COBOL V5.1, we also need to specify a maximum number of occurrences in the syntax , and hence a maximum size for the table and the containing group, which causes usability problems in some contexts. In particular, this problem occurs when defining... [More]
Did you know that IBM COBOL for AIX does not charge for runtime deployment ? Yup, you heard that right. As part of your COBOL for AIX, V4.1 development license, not only do you get the latest advanced compilation technology from IBM, but you may also redistribute the COBOL for AIX, V4.1 runtime along with your COBOL application at no extra cost . This directly results in a lower total cost of ownership compared to other solutions -- positively impacting your bottom line! Couple this with the latest advancements in POWER7 technology AND the...

In this section of the Cafe you will find various bits of technical info - all about making the most of your RDz work-time. While Dave Myers and I are the primary content managers for this blog - and will be responsible both for new posts and reviews, we are more than happy to make you famous (at least within the fraternity of RDz developers) by posting your Tips&Techniques. Any takers? (talk again soon) - Jon Sayles
Rational Developer for Power Systems Software is a modern,
Eclipse-based, multi-lingual, integrated development environment
targeting POWER Linux, AIX, and IBM i systems. This video will show you some of the highlights and features covered in the Innovate 2011 COBOL workshop. If you missed Innovate2011, then check out the same exercises shown in the video at the IBM Enterprise Modernization Power Systems sandbox. Explore COBOL development for AIX using modern tools ( Request a user ID and password before you start this scenario.)
IBM® COBOL for AIX®, V4.1.1 delivers various performance improvements in
the COBOL runtime libraries that can help your applications run faster,
enhanced I/O functionality, and productivity enhancement. This release gives you improved performance for COBOL for AIX applications that use packed arithmetic and conversion to and from packed arithmetic dynamic calls, external variables, external files, as well as module caching This release also delivers improved file I/O performance and functional enhancements, enables you to directly access a...

This is the fifth 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. In my most recent blog entry I described some improvements for listing the contents and attributes of COBOL tables (arrays). In this entry I'll continue exploring Debug Tool's support for tables, and how it has improved with COBOL 5.1, providing better usability and support for COBOL... [More]
With Enterprise COBOL for z/OS V5.1.1, the LIST option output in the compiler listing is enhanced to include a new special register table . There you can find the location information for all the COBOL special register variables. The offset to the table can be found in the second entry of the PPA3, and the offset is relative to the starting address of the PPA3.The special register table format is similar with that of the base locator table. The following example further explains the special register table: Each entry in the special... [More]
