<br>
If case.joint is ok, opticplot "J" should be possible.<br>
Only for the other options, the necessary files are created by kram.<br>

It is free.<br>

<br>
Why should your files be erased when you use a new compiler ?<br>
You need to learn and understand the dependency of different steps.<br>
A new compiler can even be used alternatively to your old one by just <br>
changing your environment (path) correspondingly. But after <br>
installation, it changes the FORTRAN programs (when you recompile all of <br>
them), but not your data.<br>
