What about relations when using a numeric PK?, this is right out of Fox Help for set relation:

"If eExpression1 is numeric, it is evaluated when the record pointer in the parent table is moved. The record pointer in the child table is then moved to record number eExpression1"

eExpression1 is of course the relational expression, maybe I'm missinterpreting this, I've never actually tried it, but it sounds like something I don't want, anyone want to shed some light on this?
