This document specifies the form and establishes the interpretation of
programs expressed in the High Performance Fortran (HPF) language. It
is designed as a set of extensions and modifications to the established
International Standard for Fortran (ISO/IEC 1539:1991(E) and ANSI
X3.198-1992), informally referred to as ``Fortran 90'' ([12]).
Many sections of this document reference related sections of the
Fortran 90 standard to facilitate its incorporation into new standards,
should ISO and national standards committees deem that desirable.
