Optimizing modules

To use the Automatic Binary Optimizer for z/OS®, write your JCL for the optimization process.

Invoking ABO with the EXEC statement

Use the EXEC job control statement in your JCL to invoke ABO. The EXEC statement is as follows:

  //OPT      EXEC PGM=BOZOPT

Required DD statements

The optimization process requires that you specify data sets for specific uses in the optimization process. You can define these data sets in DD statements with the required ddnames. The ddnames that are used by ABO and their characteristics are shown in Table 1.

Specifying the optimizer directive BOPT or IEFOPZ

Use BOPT or IEFOPZ to direct ABO. You can include one or more of the BOPT or IEFOPZ directives in the SYSIN DD. For details, see BOPT and IEFOPZ.
