From the world’s best checking Fortran Compiler to technology licensing NAG's Fortran Compiler Test Suite

NAG developed the worlds’ first Fortran 90 Compiler in the 1990s, which has continued to evolve through many iterations to today’s NAG Fortran Compiler. Proven to be highly accurate and indispensable for its checking capabilities, the associated NAG Fortran Compiler Test Suite is today used by most of the other Commercial Fortran Compiler writers and like our compiler continues to be developed in line with the Fortran Standard by its original creator, Malcolm Cohen, NAG Principal Technical Consultant.
