IF your lists are archived the date of each file making up the archives for
a list is a very good indicator of the 'last used' date.
While I am doing this from VM on the mainframe, the same technique should
work on other platforms. I have an exec (script) that runs weekly and pulls
a list of the current lists, parses their headers for basic info and updates
an info file with new lists. Since our standard for list headers requires
the keyword pharse: "CLASS LIST FOR xxxxxxxx" I can distinguish the class lists
from the others. The date the record is created (first time list is seen)
and a keyword identifying the list as a class list, then allows me to run
another script after semester's end to generate delete commands for the archive
files. I leave the list defined and our support staff does deletes after the
next term starts.
