  35    SHOW+1 is the maximum number of levels of internal type structure
  36       to show (this applies to record types, enumerated types, and
  37       array types).
  38    SHOW is the number of levels of internal type structure to show
  39       when there is a type name for the SHOWth deepest level (0th is
  40       outer level).
  41    When SHOW<0, no inner structure is shown.
  42    LEVEL indicates level of recursion (for nested definitions).  */
