7    CHANGED:  Database error handling
------------------------------------------------------------------------------

      In Clipper 5.01, using database commands without an
      open work area would not cause an error. With the
      following exceptions, Clipper 5.01a now produces a
      "Work area not in use" error.

      The following table shows "state query" functions
      that do not produce a "Work area not in use" error.
      This list indicates the return value of these
      functions when executed without an open work area.

      Table: State query functions and their return
      value with no open work area.
