![]() ![]() ![]() FABLE is available under a nonrestrictive open source license. With FABLE it is possible to reuse and evolve legacy work in modern object-oriented environments, in a portable and maintainable way. Our experience suggests that most Fortran 77 codes can be converted with an effort that is minor (measured in days) compared to the original development time (often measured in years). We report the application of FABLE in three major projects and present detailed comparisons of Fortran and C++ runtime performances. This enables the continued development of new methods even while switching languages. The many tools accumulated during this time have been difficult to integrate with modern software, which is now dominated by object-oriented languages.ĭriven by the requirements of a large-scale scientific software project, we have developed a Fortran to C++ source-to-source conversion tool named FABLE. In scientific computing, Fortran was the dominant implementation language throughout most of the second part of the 20th century. ![]()
