[petsc-dev] make all PETSc Fortran examples modern freeform?

[Blaise A Bourdin]

Would it be possible to remove all instance of the "PARAMETER” keyword from the petsc source code? I would like to compile a FORTRAN IV boundary element program I wrote in 1963 for the structural analysis of 8 track cartridges.
Also, where do I get a punch-card version of petsc source code? I cannot compile git on my IBM 7030.
