# TEST test031
# TEST Duplicate sorting functionality
# TEST Make sure DB_NODUPDATA works.
# TEST
# TEST Use the first 10,000 entries from the dictionary.
# TEST Insert each with self as key and "ndups" duplicates
# TEST For the data field, prepend random five-char strings (see test032)
# TEST that we force the duplicate sorting code to do something.
# TEST Along the way, test that we cannot insert duplicate duplicates
# TEST using DB_NODUPDATA.
# TEST
# TEST By setting ndups large, we can make this an off-page test
# TEST After all are entered, retrieve all; verify output.
# TEST Close file, reopen, do retrieve and re-verify.
# TEST This does not work for recno
