* From D.95A on, there is an ARR segment that should be altered.
  The Composite C770 should be there 100 times, and in the C770
  field 9424 should be there 100 times. The special C770.def should
  be inserted at the C770 definition in the ARR segment in the
  ??SD.* file and the existing C770 lines should be deleted from
  the segment definition.
  Look at the Note: part to check the ARR definition with the 
  provided C770.def file.
