Re:

Jon,

You bring up a good point.  Although the getFromArray was the fastest
method tested, Nathan might have been getting the first entry with each
evocation.

Getting the middle entry with a binary search may change the results of
the test a bit.

BTW, Nathan: when I spoke of putting the file in memory I was thinking
more of using the SETOBJACC (Set Object Access) which acts like the old
RAM disk and still using CHAIN to read it.
