Jim,

>From what I've tried in VFP 5.0, W95 (the data reside on a local disk,
have not tried on the shared novell drive yet), transacation processing
does not lock the whole table: I locked a record on station (with
rlock()), and could update another record in the same table from within
a transaction on another station. The transaction fails if the same
record is updated, but that is to be expected.

HTH,

Marc
