On-Line Fortran F77 - F90 Converter

Polyhedron Software offers this limited free service allowing anyone to submit their Fortran 77 source code and to view the converted and restructured code after being processed using the SPAG feature of Polyhedron's PlusFort toolset. The conversion options given here are only a very small subset of those available in the full package and the only other limitation is that each routine is restricted to 100 lines.
Instructions
Paste your code into the F77 code window, choose your conversion options and press SUBMIT. The converted code will appear in the F90 code window and a log of the conversion process can be viewed by pressing the 'show output log' button.
