    PRINT      Sequential -- F, L-D, N
    READ       Sequential -- F, U, L-D, N
               Direct Access -- F, U
               Internal -- F, L-D
               Indexed -- F, U 
    REWRITE    Relative -- F, U
               Sequential -- F
               Indexed -- F, U 
    TYPE       Sequential -- F, L-D, N
    WRITE      Sequential -- F, U, L-D, N
               Direct Access -- F, U
