I'm wondering how large is your data set? The technique of reading back to pick
up the last three records would be necessary for HUGE data files, but more
work than necessary for smaller sets (of, let's say, 10 - 20,000 lines).
Better and faster to just read them into a sequence, and use the portion you
want,  especially since you eventually want the data in an array anyway.

If you really are reading huge data sets, maybe a better way would be to
find the end of the file, then read backwards until you count 3 linefeeds, then
read forward from there.
