Intrinsic and Library Procedures

HPF includes Fortran 90's intrinsic procedures. It also adds new intrinsic procedures in two categories: system inquiry intrinsic functions and computational intrinsic functions.

The definitions of two Fortran 90 intrinsic functions, MAXLOC and MINLOC, are extended by the addition of an optional DIM argument.

In addition to the new intrinsic functions, HPF defines a library module, HPF_LIBRARY, that must be provided by vendors of any full HPF implementation.

This description of HPF intrinsic and library procedures follows the form and conventions of Section 13 of the Fortran 90 standard. The material of Sections 13.1, 13.2, 13.3, 13.5.7, 13.8.1, 13.8.2, 13.9, and 13.10 is applicable to the HPF intrinsic and library procedures and to their descriptions in this section of the HPF document.
