Hi Gavin,
I believe that VFP locks the table *header* on a REPLACE...FOR statement.
However, is your FOR expression Rushmore optimizable? It seems to me that in the dark recesses of my (admittedly swiss-cheese) memory, I recall that if it is, and you're updating only one field in a single table, VFP does *not* lock the header.
(searching internal FAQ's...that might take a while)(bg)
HTH.
