APF Library Statistics Summary

APF‑authorized libraries can contain programs with nonzero authorization codes that permit them to run as APF‑authorized job-step tasks. It is important to know the number and location of all APF‑authorized programs in the system. It is even more important to know the location of the APF‑authorized superzap (AMASPZAP) programs on the system. The locations of these programs are important because they can alter or zap a volume table of contents (VTOC). APF‑authorized libraries are specified in the IEAAPFxx and LNKLSTxx members in the logical parmlib.

The APF Library Statistics Summary display shows a summary of information about APF libraries on the system. CA Auditor identifies the APF libraries and then summarizes the information about these libraries on the display. CA Auditor also lets you take a more detailed look at the APF libraries on the APF Library Statistics Detail Display, which displays when you press Enter. CA Auditor marks any APF‑authorized superzap programs that it recognizes on the detail display.
