HPF-Conforming and Subset-Conforming Up: Overview Previous: Fortran 90 and


This document uses the same notation as the Fortran 90 standard. In particular, the same conventions are used for syntax rules. BNF descriptions of language features are given in the style used in the Fortran 90 standard. To distinguish HPF syntax rules from Fortran 90 rules, each HPF rule has an identifying number of the form H, where is a one-digit major section number and is a one- or two-digit sequence number. The syntax rules are also collected in Annex . Nonterminals not defined in this document are defined in the Fortran 90 standard. Also note that certain technical terms such as ``storage unit'' are defined by the Fortran 90 standard; Annex identifies the Fortran 90 rules defining these nonterminals. References in parentheses in the text refer to the Fortran 90 standard.
