Indicates whether or not a cursor is positioned at the first record in a dataset.
property Bof: Boolean;
Test Bof (beginning of file) to determine if the cursor is positioned at the first record
in a dataset. If Bof is True, the cursor is unequivocally on the first row in the dataset.
Bof is True when an application:
- Opens a dataset.
- Calls a dataset's First method.
- Call a dataset's Prior method, and the method fails (because the cursor is already on the first row in the dataset).
- Calls SetRange on an empty range or dataset.
Bof is False in all other cases.
