On-Line Fortran F77 - F90 Converter

This free service, offered by Polyhedron Solutions, allows you to submit your Fortran 77 source code (up to 500 lines), and to view the result of processing it using SPAG - part of Polyhedron's plusFORT toolset. A very small subset of the customization options available in the full plusFORT package is available using the drop-down boxes.

Instructions
Cut and paste your code into the F77 code window, or, if you don't have something ready, click "Load Our Example Code". Then, choose your conversion options and click SUBMIT. The converted code will appear in the F90 code window and a log of the conversion process can be viewed by clicking the 'show output log' button.
