What IBM Automatic Binary Optimizer for z/OS can do

IBM® Automatic Binary Optimizer for z/OS® (ABO) is advanced COBOL optimization technology to target the latest IBM Z® systems. ABO reduces CPU usage and operating costs by directly optimizing COBOL modules that are compiled with VS COBOL II 1.3 to Enterprise COBOL 6.4. ABO does not require recompilation or compiler migration and maintains strict compatibility to the original modules. As a result, testing costs can also be significantly reduced. 

New in ABO 2.2 is the ability to optimize Enterprise COBOL 5 and 6 compiled modules. This enables you to future proof your COBOL application performance and minimize build complexity. 

When optimizing modules that are produced by earlier COBOL 4.2 and earlier compilers, ABO can achieve comparable performance to the latest build compilers. Therefore, ABO can also help reduce your migration effort to Enterprise COBOL 6. You need to only migrate source being actively developed and then use ABO to improve the performance of all the other modules that do not have a recompilation plan. 

The ABO Assistant, included in ABO 2.2, simplifies an ABO evaluation, and accelerates deployment of your ABO optimized batch and CICS® applications.  


Lower operating costs with optimized programs

ABO-optimized modules behave the same way as the original modules, but consume fewer CPU resources and have shorter processing time.

Quickest time to value

ABO can achieve comparable performance as the latest Enterprise COBOL compiler. Optimizes modules with reduced testing costs. Simplified evaluation and accelerated deployment with ABO Assistant.

Team up: ABO and Enterprise COBOL

ABO and COBOL are built to work together. Use COBOL 6.4 for active development and ABO to optimize programs not frequently compiled. Future proof performance and simplify complex build environments.

Currency = maximizing ROI

IBM Z delivers application performance with hardware features and advanced optimization technology. It is important to stay current with Enterprise COBOL and ABO.
