Maximize hardware utilization, reduce CPU usage, and improve performance of critical applications
IBM Enterprise Cobol for z/OS® is a programming language used to develop applications for data processing on IBM z/OS.
To maximize your IBM z/Architecture® ROI and improve performance of your business-critical applications, stay current with IBM Enterprise COBOL for z/OS compiler and IBM Automatic Binary Optimizer for z/OS (sold separately) and selectively optimize CPU-intensive parts of the applications.
IBM Enterprise COBOL for z/OS works with infrastructure technologies with native support for JSON, XML, and Java® and AMODE 64 (64-bit), including interoperability with AMODE 31 (31-bit).
For the latest updates for IBM Enterprise COBOL for z/OS.
Reduces CPU utilization and operating costs by utilizing the COBOL compiler's leading edge optimization technology and ability to exploit the latest IBM Z® hardware and middleware.
Improves productivity by leveraging new usability features to simplify programming techniques, problem determination, and support tools supplied by IBM and other ISVs.
Modernizes your applications with features that have been extended to support web, cloud, and mobile infrastructures.
Compatible with earlier COBOL compilers with no need to recompile an entire application to use features from the latest release.
Use the latest version of Enterprise COBOL for new development, modernization and maintenance. Use ABO (sold separately) to improve the performance of the COBOL modules without a recompilation plan.
Generate code to take advantage of IBM z16™, IBM z15™, IBM z15 T02, IBM z14®, IBM z14 ZR1, IBM z13®, IBM z13s®, IBM zEC12 or IBM zBC12 processors without the need for source code changes. In addition, it increases hardware ROI by incorporating leading edge optimization technology.
Supports the Continuous Delivery (CD) model so that you can receive new features and enhanced capabilities as soon as the code is ready. You can now receive enhancements in a faster and more continuous way without waiting for the next release.
Introduces compiler enhancements such as new compiler options to detect or correct invalid data issues, which help ease your migration efforts from COBOL 4 or earlier to COBOL 6 or later compiler. In addition, the one-stop COBOL Migration Portal contains all the COBOL migration-related information to support your migration.
Use the latest version of Enterprise COBOL for new development, modernization and maintenance. Use IBM Automatic Binary Optimizer for z/OS (ABO), sold separately, to improve the performance of the COBOL modules without a recompilation plan.
Get easier problem determination and support for modern development tools that are supplied by both IBM and other ISVs and support of simplified programming techniques.
IBM COBOL Report Writer is a separately orderable product that runs with the IBM COBOL compiler. It produces all the listings, reports and displayed summaries required in a COBOL application and users can significantly reduce the time and effort needed to code and test a program with printed output.
