                     11:     This file contains structures and defines that are used
                     12:     specifically for the tape drivers. Contains #define's,
                     13:     function protypes, etc. for use in calling functions in
                     14:     physlogi.c that do physical to pseudo-logical and pseudo-
                     15:     logical to physical tape block address/position translation.
