In Foxpro if you do a
GOTO 7
with deleted off and record 7 is deleted, the record pointer doesn't
move (at least in version 6).
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)

Even with a break, why bother continuing through the body of the function
when you already have the result? When your calculation is done, it's
done, just return for goodness sake. You wouldn't write a search that
keeps going after

Getting closer to a stable release.
Latest version has a simpler, cleaner API, and works on PyPy (and
hopefully the other implementations as well ;), as well as CPython.
Get your copy at http://python.org/pypi/dbf.
Bug reports, comments, and kudos welcome! ;)

Excellent! That's fantastic news! I've been waiting for a stable release
of dbf for months! I just have one question.
What is dbf?

Question 1 - What version of VFP will dbf work with? Is VFP9 OK?
As long as you don't use auto-incrementing fields nor varchar fields
you'll be fine.
Question 2 - You statement of compatibility is unclear.
Works with CPython 2.4 - 2.7. (Tested)
Works with PyPy

Have you considered supporting 3.2/3.3 at all? It's often not
difficult to make your code compatible with both. Or is there some
dependency that is locked to 2

The trouble with double-codebasing is that you have double
maintenance. But sure. So long

Leaving aside the point that this is not directly related to Python, my
opinion is that if the authors will not make past and future papers
