That can be a problem! Just added the value -2,147,483,648 to an int field on SQL server and ran a sql pass-thru query in VFP against that table and the field comes back as an int in VFP but contains **********

This is a pretty big compatibility issue! Do you think it should be fixed by the VFPT ?
