Benefits

Using IBMAutomatic Binary Optimizer for z/OS (ABO) to optimize your COBOL applications lowers your IBM® Z operating costs. The ABO- optimized modules behave the same as the original modules but consume fewer CPU resources and have shorter processing time.

Using ABO offers the quickest time to value. ABO 2.3 delivers comparable performance benefits to the latest Enterprise COBOL 6 compiler. ABO directly optimizes already-compiled modules and testing cost is significantly reduced. Using the ABO Assistant, an evaluation is simplified, and deployment is accelerated.

Using ABO allows you to maximize the return on investment (ROI) of your IBM Z server. IBM Z® servers deliver performance with hardware features and advanced optimization technology. COBOL applications compiled by earlier COBOL compilers do not use new hardware instructions available on the latest IBM Z servers. Optimizing the earlier COBOL applications with ABO delivers up to a 25-year jump forward in the evolution of hardware technology, with access to over 600 new hardware instructions that are on the ABO, IBM z16®, IBM z15®, and IBM z14 servers.

ABO and Enterprise COBOL are designed to work together. Use IBM Enterprise COBOL for z/OS® to compile programs that are under active development; and ABO to optimize programs that are not frequently compiled.

ABO can optimize modules including the latest Enterprise COBOL compilers. This enables COBOL developers to use the best set of compiler options during development, debug and test for the fastest application delivery. ABO can be used for the best production performance with significantly reduced build complexity and testing cost.
