1

Detect superzap activity.

Search each of the key z/OS libraries for zapped modules. Verify that changed modules agree with change authorization records and procedures.

2

Find programs that are really renamed utilities, such as superzap.

Enter SORT DATE SIZE to reorder the list of programs according to link‑edit date and linked size. If any programs have the same date and size as a utility, browse the duplicate.

3

Determine compile and linkedit dates.

Select a sample of programs from the production load libraries that were linked during a given time period. Verify that the dates agree with change authorization records and procedures.

4

Identify the use of subroutines in production load libraries.

Select a sample of programs from this display to obtain CSECT information on the Program CSECT Display. Note which subroutines were used and verify that adequate documentation is available that defines their purpose, use, and function.

5

Gather information about the size of load modules, performance tuning, and adherence to standards.

Select a library and identify its smallest and largest members to ensure that they conform to data center standards.

6

Detect unwanted APF‑authorized programs in application load libraries. Obtain the library names using the Link List Library Display (2.4.2), and then identify any APF‑authorized programs using the Program Statistics Display (5.2). Repeat the test with a sample of private load libraries.

7

Evaluate the progress of program conversion projects that change a system from one programming language to another.

Obtain the names of libraries under conversion from the data center. Select a sample of programs and note the language displayed for each. Calculate completion figures and compare your figures with published status reports.
