IBM Enterprise COBOL for z/OS® is a premier enterprise class COBOL compiler for IBM z/OS. It delivers innovation for modernizing business-critical applications, programming features to increase programmer productivity, and bolsters the overall benefits of transactional and data systems such as IBM CICS®, IBM IMS, and IBM Db2®.

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).

Features

• **Utilize IBM z16 hardware features: **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.
• **Continuous delivery of enhancements: **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.
• **Easy migration: **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 Enterprise COBOL and Automatic Binary Optimizer together: **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.
• **Improve productivity: **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.
• **Modernize applications: **Modernize your environment to support web, cloud and mobile infrastructures, while reducing cost, risk and cycle time including RESTful JavaScript™ Object Notation (JSON) services with traditional XML web services, Native UTF-8 to efficiently communicate across applications, AMODE 64 (64-bit) batch applications development, interoperability between AMODE 31 (31-bit) and AMODE 64 (64-bit) COBOL programs and improved COBOL/Java interoperability.
• **COBOL Report Writer support: **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.

Benefits

• **Optimize performance: **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.
• **Accelerate time-to-value: **Improves productivity by leveraging new usability features to simplify programming techniques, problem determination, and support tools supplied by IBM and other ISVs.
• **Modernize your applications: **Modernizes your applications with features that have been extended to support web, cloud, and mobile infrastructures.
• **Compatible with earlier COBOL compilers: **Compatible with earlier COBOL compilers with no need to recompile an entire application to use features from the latest release.
• **Enterprise COBOL and Automatic Binary Optimizer (ABO) team up: **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.
