      The following macro invocation is to ensure that no
      CHANGES ARE MADE TO THE SIZE OF THIS CONTROL BLOCK WITHOUT
      PAYING ATTENTION TO THIS BLOCK COMMENT.
      THE   FSAIDXSH EQUATE IS USED TO FORM FSATE OFFSETS BY
      SHIFTING ZONE NUMBERS.  THIS WAY OF FORMING FSATE OFFSETS
      DEPENDS ON THE SIZE OF THE FSATE BLOCK BEING A POWER OF 2.
      IF THIS CONTROL BLOCK SIZE SHOULD CHANGE, THE FSAIDXSH
      MUST ALSO CHANGE, SO LONG AS THE NEW SIZE IS A POWER OF 2.
      IF NOT, ALL USES OF FSAIDXSH MUST BE CHANGED TO FORM
      FSATE OFFSETS BY MULTIPLYING ZONE NUMBER  BY THE FSATE
      CONTROL BLOCK LENGTH.
