Processing a List
This is the preferred method for processing lists. To correctly process through a
list, do the following:
1. Use the offset to list data section field (see 5 on page 5-9)
2. Look at the number of list entries field in the list (see 6 on page 5-10)
3. Add the size of each entry field to get to the start of the next entry (see 7 on
page 5-9)
IBM may add fields to the bottom of formats in future releases. If this occurs and
your code uses the size of each entry for a previous release, your list would not
process at the start of each entry.
The example program defines the size of each entry at 4 on page 5-9. For
another example that shows the correct and incorrect way, see “Defining List Entry
Format Lengths” on page 9-14.

The example program prints a report that shows all objects that adopt owner
authority.
