COBOL module requirements

The input to the IBM® Automatic Binary Optimizer for z/OS® is your COBOL program modules. ABO verifies that the program modules provided are supported by ABO. ABO then scans the CSECTs within the program modules for those that are eligible for optimization. A CSECT is eligible for optimization by ABO if all of the following conditions apply:

• It was generated by an eligible IBM COBOL compiler.
• All the COBOL language features and options are supported.
• The optimization verification passes all succeed.
