An important practical extension to FORTRAN 77 was the release of MIL-STD-1753 in 1978. [37] This specification, developed by the U.S. Department of Defense, standardized a number of features implemented by most FORTRAN 77 compilers but not included in the ANSI FORTRAN 77 standard. These features would eventually be incorporated into the ...
PAW is a free data analysis package developed at CERN. Portable, Extensible Toolkit for Scientific Computation (PETSc), is a suite of data structures and routines for the scalable solution of scientific applications modeled by partial differential equations. QUADPACK is a FORTRAN 77 library for numerical integration of one-dimensional functions
This standard, designated FORTRAN 77, introduced many new statements into the language. In fact, the previous language standard FORTRAN 66 is a very small document and describes, what is in effect, a subset of most implementations of FORTRAN. For example, the WATFIV and WATFOR-11 implementations are based upon the IBM definition of FORTRAN-IV.
LAPACK was originally written in FORTRAN 77, but moved to Fortran 90 in version 3.2 (2008). [3] The routines handle both real and complex matrices in both single and double precision. LAPACK relies on an underlying BLAS implementation to provide efficient and portable computational building blocks for its routines. [2]: "
Simply Fortran is an Integrated Development Environment (IDE) for GNU Fortran (which currently implements FORTRAN 77, Fortran 90, Fortran 95, Fortran 2003 and Fortran 2008). [1] The project is maintained by the company Approximatrix, LLC .
One of the major features of FORTRAN 77 was the CHARACTER string data type. Use of this data type dramatically simplified character manipulation in Fortran programs – rendering almost all uses of the Hollerith constant technique obsolete.

SLATEC Common Mathematical Library is a FORTRAN 77 library of over 1,400 general purpose mathematical and statistical routines. The code was developed at US government research laboratories and is therefore public domain software.
