I was thinking last night, as I was sleeping, that I'm not even happy
with this result. the problem is what happens if you drop a data point
far off the existing data, so that, say, you have an array of 100 and 10
items in the array in positions from 0-10. Then I InsertByPosition,
into spot 61. You have junk between L.a[L.last] and L.a[60] (the 61st
position).

You need to clean all that out so you have to have a third condition
within that function for insertions past last and before the end of the
array.

Also, this whole thing should be rewritten with pointers.

intpt * = L.a; and then do the math like that. It is much cleaner and
professional code.
