Editing Fortran (section)

====Obsolescence and deletions====
Unlike the prior revision, Fortran 90 removed no features.<ref>ANSI X3.198-1992 (R2002) (Fortran 90), Appendix B.1.</ref> Any standard-conforming FORTRAN 77 program was also standard-conforming under Fortran 90, and either standard should have been usable to define its behavior.

A small set of features were identified as "obsolescent" and were expected to be removed in a future standard.  All of the functionalities of these early-version features can be performed by newer Fortran features.  Some are kept to simplify porting of old programs but many were deleted in Fortran 95.
