VMS Help PASCAL, Data Types, Ordinal  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The values in an ordinal type have a  one-to-one  correspondence
  with  the  set  of positive integers.  The values are ordered so
  that each has a unique ordinal value indicating its position  in
  a list of values of that type.
