NAG Fortran Compiler 5.3

NAG Fortran Compiler 5.3 has extensive support for both legacy and modern Fortran features, and also supports parallel programming with OpenMP. It is very exact in the interpretation of Fortran standards and incorporates cutting-edge checking features for Fortran, such as dangling pointer detection (detect use of pointers whose targets have disappeared), runtime detection of errors in procedure calls, detection of undefined variables, and memory leak detection (show where memory is not deallocated correctly). The Microsoft Windows version of the Compiler, NAG Fortran Builder, will be updated later this year.
