Cover letters provide information about
the fixes that they accompany. They explain the contents of a fix, the problem
that the fix resolves, special instructions that are associated with the fix,
and prerequisites or corequisites that must also be installed on your system
for the fix to function properly. 
You can view your cover letters with any of the following methods:
- Display PTF Cover Letter (DSPPTFCVR) command
- Display PTF (DSPPTF) command
- Fixes inventory in iSeries™ Navigator. (Refer to Display an inventory of fixes on your server with Management Central.)
You receive cover letters electronically as physical file members or on
the particular media with the fixes. The cover letters are stored in members
of file QAPZCOVER in library QGPL and are named Q pppppppxx, where ppppppp is
the fix ID or a timestamp depending on what the fix save file was named. The xx are
the last two digits of the language code of the cover letter. For cover letters
in English, the last two digits of the language code do not appear, and the
member name is the same as the corresponding fix save file name. For
a list of tasks associated with fix cover letters, see Work with fix cover letters.
