I don't like that.
I see four other options:
0) don't move the pointer (listed for completeness)
1) go to that record anyway
2) go to the next undeleted record
3) go to the seventh undeleted record (possibly the least practical)
4) raise an exception
Any opinions?
What happens when you 'delete' a record? Does it disappear immediately,
or is it merely marked for deletion?
If it is marked for deletion, can it be unmarked? Will a marked record
be removed when the file is closed, or does the file need to be
explicitly purged/compacted?
If it is merely marked, then I think the best option is 1, or possibly
4 if the file is compacted when closed.
