Well, let's see...

A couple more days to have the datetime bit worked out (I don't support 
datetimes prior to 1981 in vfp tables),
longer for currency types, and of course, no idx/cdx support at this point.

Tell you what --  I'll trade you a copy of the code as it stands with 
date and datetime working for null values, for an answer of whether you 
need idx/cdx file support.  ;)
