Overview

IBM® Enterprise COBOL for z/OS® is a leading-edge, z/OS-based compiler that helps you create and maintain mission-critical, line-of-business COBOL applications to execute on your z/OS systems. Enterprise COBOL for z/OS continues to give you access to CICS®, DB2®, IMS™, and other transactional and data systems.

Enterprise COBOL for z/OS is enhanced to support the continuous delivery model. Continuous delivery allows you to receive new and enhanced capabilities through the compiler service channel. New features and enhancements are included in Program Temporary Fixes (PTFs) along with corrective and preventative service.

With continuous delivery, you benefit in receiving the new features that you need as soon as the code is ready. You can now receive enhancements in a faster and more continuous way without having to wait for the next release.

Continuous delivery is already available for Enterprise COBOL for z/OS, V6.1 with the inclusion of selected features and enhancements within recently available PTFs. Among these additional features are enhancements that you requested to address urgent needs and are made available continuously through the compiler service channels to deliver:

  • INITCHECK (A new compiler option to tell the compiler to look for unitialized data items)
  • Support for Dynamic storage in COBOL (PIC X(1)) linkage section items

Continuous delivery features for Enterprise COBOL for z/OS, V6.1 are also made available in conjunction with this announcement to help you find occurrences of invalid data. The following are the features delivered:

  • NUMCHECK compiler option to check zoned decimal (NUMERIC USAGE DISPLAY) and packed decimal (COMP-3) data items for invalid data, and binary data items for digits exceeding what the picture clause allows.
  • SSRANGE (MSG) and SSRANGE (ABD) suboptions to control the runtime behavior of the COBOL program when an invalid subscript is detected.

New features that are delivered through continuous delivery are often controlled by compiler options or by usage of a new function. This gives you the flexibility to control when you implement the new feature in your environment. The two features made available in this continuous delivery release are implemented by you using options or suboptions.

Introduction of the continuous delivery model for these enterprise-level programs reinforces the continuing IBM commitment to the COBOL programming language on the IBM z™/OS platform. With the support of the continuous delivery model, you gain the benefit of immediate delivery of new compiler technology and new functions while taking advantage of more than 50 years of IBM experience in compiler and compiler related development.

Description
Bottom rule

The continuous delivery model for Enterprise COBOL for z/OS, V6.1 is already implemented with the inclusion of features and enhancements within recent PTFs as follows:

  • INITCHECK (available with APAR PI68226). INITCHECK is a new compiler option to tell the compiler to look for uninitialized data items.
  • Support for dynamic storage in COBOL (PIC X(1)) linkage section items with reference modification and table ODO overlays (available with APAR PI63286).
Continuous delivery features for Enterprise COBOL for z/OS, V6.1 which are available with this announcement include:

  • NUMCHECK (available with APAR PI71625: This APAR requires z/OS Language Environment® PTF with APAR PI72127)

    The NUMCHECK compiler option tells the compiler whether to generate extra code to validate data items when they are used as sending data items. For zoned decimal (numeric USAGE DISPLAY) and packed decimal (COMP-3) data items, the compiler generates implicit numeric class tests for each sending field. For binary data items, the compiler generates SIZE ERROR checking to see whether the data item has more digits than its PICTURE clause allows.

    Note: ZONECHECK is deprecated but is tolerated for compatibility, and it is replaced by NUMCHECK(ZON).

  • SSRANGE suboptions MSG and ABD (available with APAR PI74933: This APAR requires z/OS Language Environment PTF with APAR PI72127).

    This option is enhanced with new MSG and ABD suboptions that control the run-time behavior of the COBOL program when a range check fails. If MSG is in effect and a range check fails, a run-time warning message is issued and the program will continue executing and may potentially identify other out-of-range conditions. If ABD is in effect and a range check fails, the first out-of-range condition will result in a run time error message and the program will abend.

Many new features are inactive until used. These features are controlled by compiler options or by your usage of a new function. Generally, you must make a code change to your application or invoke new compiler options in order to activate any new function.

Some features are not activated by an option or code change made by you to your application but instead are active by default as soon as you install the continuous delivery PTF. Examples of these kind of features are general performance enhancements (for example, performance tuning or fixes), minor listing changes, and message changes.

Continuous delivery features apply primarily to the service stream of the latest active release of the product. Once a new version or release is made available, it becomes the latest service stream which receives continuous delivery features. The previous release reverts back to corrective or preventative service only.

Ordering z/OS through the internet

Shopz provides an easy way to plan and order your z/OS ServerPac or CBPDO. It will analyze your current installation, determine the correct product migration, and present your new configuration based on z/OS. Additional products can also be added to your order (including determination of whether all product requisites are satisfied). Shopz is available in the US, Canada, and several countries in Europe. In countries where Shopz is not available yet, contact your IBM representative (or IBM Business Partner) to handle your order through the traditional IBM ordering process. For more details and availability, go to the Shopz website.

Unlicensed documentation

A Program Directory and Licensed Program Specifications are supplied automatically with the basic machine-readable material of the base release. No other hardcopy publications are shipped with the product.

The Enterprise COBOL for z/OS,V6.1 Knowledge Center and PDFs are updated to document the continuous delivery features. No other publications are updated or shipped with continuous delivery features.

Subsequent updates (technical newsletters or revisions between releases) to the publications shipped with the product will be distributed to the user of record for as long as a license for this software remains in effect. A separate publication order or subscription is not needed.

Customized Offerings

Product deliverables are shipped only through CBPDO and ServerPac. These customized offerings are offered for internet delivery from Shopz. Internet delivery reduces software delivery time and allows you to install software without the need to handle tapes.

Statement of good security practices
Bottom rule

IT system security involves protecting systems and information through prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a lawful, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective.

Important: IBM does not warrant that any systems, products, or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.
