You may wish to retain this package for future use. When you install additional operating system software you will want to use this package to bring the additional software up to this level.

You can create a list of the APARs closed in this package, which you can then view (and search) in an ASCII editor, such as vi or emacs. First, create the .toc file for the package by using the inutoc command described above. Then, run the following command to extract the APAR listings from the .toc file:

grep ^I .toc > apar.list

Run the following command to eliminate duplicate entries from the apar.list file:

sort -u apar.list -o sorted.apars
