packed                   Data Type Modifier to Request Packed Data Structures

 packed array[...] of <basetype>;
 packed record
   ...
 end;

    In Standard Pascal, you can request arrays and records to be PACKED.
    This means that, if possible, a more compact representation of certain
    data types will be used, such as one bit per Boolean element. In Turbo
    Pascal, the PACKED keyword has no effect; packing is always done and
    is only performed to the byte (not bit) level.

  -------------------------------- Example ---------------------------------

           type
             BitTable = packed array[0..99] of Boolean;
             NameStr  = packed array[0..50] of Char;

             InfoRec  = packed record
               Displayed:   Boolean;
               XCoordinate: Integer;
               YCoordinate: Integer
             end;
