Information Technology - Programming Languages - FORTRAN - Part 1: Base Language (formerly ISO/IEC 1539-1-1997)
Comprises the specification of the Fortran language. With the limitations noted in 1.5.1, and the deletions described in Annex B, the syntax and semantics of Fortran 90 are contained entirely within Fortran 95. Therefore, [CHECK BSR-8 FORM FOR MISSING TEXT] and standard-conforming Fortran 90 program not containing deleted features or affected by such limitations is a standard-conforming Fortran 95 program. New features of Fortran 95 can be compatibly incorporated into such Fortran 90 programs, with any exceptions indicated in the text of this part of the standard.
