Hi boss, hope you're enjoying your holiday!

I had problems with Open a long time ago, and switched to calling First. I think it was that Eof occationally was true
even though the dataset contained records, but it may have been the other way around. I never checked very carefully (e.g.
maybe I forgot to call Close between repetitions?) since the fix was so simple.
