Options

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