The AUTODSN= parameter of the DISPLAY DUMP,TITLE operator command
enables you to list up to 100 of the most recent dump data sets that
were automatically allocated during this IPL. No information is preserved
about data sets that were automatically allocated before the last
100. As an example, if you wanted to see the titles of the last 5
automatically allocated dump data sets, you would issue:
DISPLAY DUMP,TITLE,AUTODSN=5
For complete information on the use of the DISPLAY DUMP command,
see DISPLAY DUMP in z/OS MVS System Commands.
