Each time the CCU starts up, or if the current logfile exceeds 10 megabytes
during program execution, the following sequence of events occurs:
The current logfile (logfile 000.txt) is closed and renamed as logfile 001.txt.
The numbers of the following logfiles are all incremented by one so that logfile
001.txt becomes logfile 002.txt, logfile 002.txt becomes logfile 003.txt, and so
on. The oldest logfile (logfile 014.txt) is deleted.
A new logfile 000.txt is opened and becomes the current logfile for subsequent
messages.
Since there may be up to 15 logfiles in the CCU directory (logfile 000.txt through
logfile 014.txt) they may consume up to a total of 150 megabytes of disk space.
However, since a new logfile is opened each time the CCU is run, each logfile
may not reach its full capacity and therefore less disk space may be consumed by
the logfiles.
