  You can specify certain characteristics of  the  record  key  by
  listing  the  desired  options on the KEY attribute.  With these
  options, you can control the order of the collating sequence and
  you can allow changes or duplicates on a key.

  See the  "Compaq  Pascal  Language  Reference  Manual"  for  the
  complete description of using these options.
