Converting from F77 to F90

[Heliax]

Greetings!

I am taking a course in Finite Element Analysis, and our term project is to create a fortran program that does this analysis. I was trained using Lahey ED4W (ver 3.80) on Windows, and very much would like to stick with using F90 for the purposes of this class. The professor said F90 would work great for the project...

Unfortunately, the skeleton program he provided to us is in Fortran 77. I have never converted a program from F77 to F90; a friend gave me a program that sort-of does it, but it doesn't do a complete job.

Is there some way I can convert an f77 program to an f90 using the ED4W editor? Or, alternatively, is there some way/code (in F90) availible that does a full conversion from one to the other?

Thank you very much for your time and help.

Sorry but the ED4W editor will not convert Fortran 77 syntax (fixed source form) ot Fortran 90 syntax (free source form).

Our Fortran 90 and 95 compilers will accept either form of syntax so it does not need to be converted to be compiled.

Tools are available to do this conversion. The plusFORT product available from the Lahey web site will convert the syntax from F77 to F90. See http://www.laheyonline.com/index.cfm
