It combines a comprehensive subroutine library with an extensive set of visual tools that simplify the design and development process. Winteracter-based applications can be totally Fortran 9x-based, eliminating the need to resort to compiler-specific features, mixed-language programming or low-level API calls. Winteracter aims to enable scientists and engineers to implement a modern graphical user interface, within a familiar Fortran-specific context.
