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.
Both IMS and Enterprise COBOL had new and exciting announcements this year. COBOL and IMS continue to deliver leading edge technologies to facilitate application integration, modernization, as well as improving application performance. Roland Koo, Product Manager for Rational Compilers, and Haley Fung, IMS Senior Developer, identify why it is important to upgrade to the latest versions of IMS and COBOL together. Speakers: Haley Fung, Roland Koo, and Kimberly Gist. Go HERE to listen to this informative podcast.
SHARE in Boston is being held August 11-16 at the Hynes Convention Center. IBM’s own “Captain COBOL”, Tom Ross, will be presenting two highly informative sessions on IBM Enterprise COBOL for z/OS, V5.1. Session 13792: ZOMG The Next COBOL Compiler Has Arrived! will discuss all of the new features that IBM’s developers have added to Enterprise COBOL for z/OS, V5.1 such as the exploitation of the latest zArchitecture, improved XML PARSE and XML GENERATE, the ability to improve the performance of your...

In addition to the fixed indicators that can be specified in the indicator area of the source reference format, there is a new floating comment indicator (*>) introduced by COBOL for AIX, V4.1. You can use the floating comment indicator in both the extended format and in the fixed format. A comment indicator indicates a comment line when specified as the first character-string in the program text area (Area A plus Area B). It can also indicate an inline comment when specified following one or more character-strings in the program text area.... [More]
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]
A playlist has been added to the Rational YouTube channel for all videos explaining how to develop COBOL on AIX using IBM Rational Developer for Power Systems Software and can be found here The newest edition is a video that explains how to get started with COBOL for AIX. It explains basic Eclipse functionality and how to use the Remote Systems Explorer to connect to an AIX machine and find files and execute commands. Edmund Reinhardt
IBM Rational Developer for Power
You may have heard about Rational Developer for Power Systems Software , which now has support for COBOL and C/C++ development on AIX as well as IBM i application development. It is easy to kick the tires by downloading the trial from here . But if you only have 3 minutes just check out the YouTube video below and be amazed at the COBOL functionality now available for AIX developers. For more information go to the product web site at http://www-01.ibm.com/software/rational/products/rdp/ .
In the previous entry on RDz's search capabilities we zeroed in on search within a file - the flexibility of RDz's search (ala' ISPF - or using the *Ctrl/F "Find/Replace" dialog*), the simplicity of using your mouse for so much of the search workflow and especially RDz's unique Search results view, that contains hyper-links to all "found" lines and elements (See "Things you might not have known about searching w/RDz Part I). Clicking hyper-links to found-elements is not only faster (and it is.. much faster than typing scads of additional... [More]
So - it's a holiday week-end (woof...) - and I'm going to make this entry short and sweet....(the barbecue awaits). Among the many reasons to use RDz - includes the fact that, while ISPF has a mature and excellent set of tools for developing z/OS apps, ISPF has been at the top (probably even down-hill/right-hand) side of the famous "Technology S Curve" - for at least two decades. http://innovationzen.com/blog/2006/08/17/innovation-management-theory-part-4/ Software innovation and enhancements - useful time and cost-saving features are seldom...

's funny - I've been using RDz for almost a year. And it seems like every time I open the product I learn something new - and find something cool/pretty cool/very cool I hadn't seen. Search - for example. Searching Withn a File Within a file Ctrl/F brings up the Find/Replace dialog (I know - you already knew that - hang in there). Find/Replace allows you to do 99% of what's available in ISPF =2. Search Search/Replace Repeat Search - if ISPF is your editor profile, you can press F5 Repeat Replace - ditto with F5/F6, just like ISPF Find All -... [More]
When you're doing z/OS maintenance and production support tasks you will routinely have to do two fairly involved analysis processes: Control Flow Analysis - where you build a "mental map" of how the PL/1 procedures and functions, COBOL paragraphs and sections or HLASM routines hang together via the operational control flow constructs in the code (PERFORM, etc.). "in the code" - means from the source code only. Data Flow Analysis - where you need to trace the flow a value within one or more programs - as it's... [More]
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
The IBM Automatic Binary Optimizer for z/OS, V1.3 Knowledge Center is refreshed today. In this February KC refresh, updates mainly include: The signature bits produced in the ABO listing transform for COBOL CSECTs are now decoded and detailed information about the CSECT are added to the listing transform. (See Listing transform contents ) Adds support to allow excluding modules from ABO processing. (See BOPT and Specifying optimization with BOPT ) Adds a summary table of ineligible COBOL modules. (See... [More]
Enterprise COBOL for z/OS, V6.2 documentation is refreshed today, to include the following enhancements: In V6.2 with the PTF for APAR PI91584 installed, add support for mixing copybooks from PDSE (or PDS) datasets and z/OS UNIX directories in a single compile: A new COPYLOC compiler option is introduced that allows you to add either a PDSE (or PDS) dataset or z/OS UNIX directory as an additional location to be searched for copy members during the library phase. For details about COPYLOC, see... [More]
