This has unanticipated results at times, especially when RI rules are considered. In many cases, the primary key is also embedded in any number of child records, and PACKing a table results in strange things happening when you need to cascade the effects of permanent deletion or record RECALL (you strand children; if you use the default RI generated by VFP, you have problems with RI and composite primary keys IAC.)

Just say NO to recycling primary keys...
