But of course, the data is NOT purged, the file size is NOT reduced!
The data is simply rendered inaccessible to you.  Does anyone know
what use to make of such settings as "Number of Tick Days to Save"
and why one would set it to less than one's tick-datafile-crunch-
copy/paste-procedure interval?  This "feature" has always struck me
as one of Omega's cruelest hoaxes.  Am I missing something here?
