In reply to Brad Sherman, who asked if there was a fast way to get map
distances out of ACEDB:

No, that is not easy yet.  The query package does in fact recognize
and handle arithmetic operations, but the output of a query must
always be a database object, or a set of objects.  In this case you
want a numeric result.  Those are obtainable in tablemaker, but I
still don't think tablemaker supports what you want.  You would have
to just obtain the map positions ofthe two genes in tablemaker, and
export the table to some other system which would do the subtraction.
