Correct.

Correct, but incomplete.  A chained DBUNLOAD followed by a DBLOAD
would preserve chronology of the *primary* chain; all bets are off
for any additional chains defined within the detail set.

My company uses DBChange, but the same principle applies.  And for those
"Oh, forget it, I'll unload/load the database anyway" moments, I usually
use the old-reliable-standby Dictionary utilities DICTDBU and DICTDBL with
their ability to use a disc-based unload file (as opposed to DBUNLOAD
and DBLOAD insisting on a tape).
