I believe that there are at least three discrepancies in the VFP Help section titled "Locking Data".

They are:
1) The table of "Commands that Automatically Lock Records and Tables" should mention...
--- that tables opened after SET EXCLUSIVE ON is in effect will cause a lock of the table(s);
--- that tables opened with the "EXCLUSIVE" clause of the USE command cause a lock of the table.
2) The discussion or table under "Unlocking Data" should make some mention of the FLUSH command to clarify its operation. It should tell us if FLUSH leaves locked records alone or if it implicitly unlocks locked records before executing or whatever the cases may be. The FLUSH entry of the Command Reference could do with mentioning this information too.
3) The table under the "Unlocking Data" section lists "SET MULTILOCKS OFF" and describes its effect as "Enables automatic release of the current lock as a new lock is secured" and the Command Reference for SET MULTILOCKS states "Switching SET MULTILOCKS from ON to OFF or from OFF to ON implicitly issues UNLOCK ALL — all record locks in all work areas are released.". I see a contradiction between the two entries. In fact I can't really understand what the first quotation is actually telling me.

Thanks
