Thanks for the feedback Adam and Ann. I've been running more tests,
and the results are much quicker than before. When I tested it the
first time, I ran it 3 or 4 times in a row and each time it took about
5 minutes. Tonight the process completes in just a couple of seconds.
There must have been some other housecleaning that it was doing
before. I've also rebooted the system since the earlier tests. I'm
very happy its running so quickly, I was beginning to think that data
input would be a major bottleneck. I apologize for not doing better
testing before. Thanks again for your input.

I love firebird!

Thanks.
