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.
