I have run test after test with two sessions of foxpro and GetFldState returns values based on the edits made in the current session only. Does any one have a reliable way to check the deletion status from disk when a table has record buffering enabled? Curval() returns the value of a field from disk, there should be some way to return deletion status from disk.
