Yes, you're correct.

>Right now, according the MS VFP9 Help file, BIT VALUE 4 openes a table in the same manner as versions prior to VFP 8. That is what we are going with right now.

The bit value 4 has no effect on opening tables w/o bit value 1 set. From the help: "Requires setting the first bit to validate record count when opening a table". IOW, value 5 validates the header on open if header can be locked. The bit value 4 alone does nothing which is the same as 0.
