Listing transform

The listing transform describes the changes made by the Automatic Binary Optimizer for z/OS® to your already compiled program module. It shows how the instructions in the input binary map to the optimized instructions. A listing transform is produced for every CSECT that is optimized. The listing transform is intended to complement the compiler listing generated when the input binary was originally compiled from source. While the listing transform does not depend on the compiler listing, using the two together will allow you to better understand how ABO transformed your binary.

A listing transform is generated unconditionally for every optimized CSECT; no special options or flags need to be specified. By default, listing transforms are generated into the SYSPRINT DD.

The listing transform is also used by Application Delivery Foundation for z/OS.
