  10
  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.
