[petsc-users] [petsc-announce] Question regarding updating PETSc Fortran examples to embrace post F77 constructs

[Pablo M. Carrica]

Hi Barry, I believe is fine to move forward with more modern Fortran. All
compilers support at least Fortran 90. Best, Pablo.

to embrace post F77 constructs


   PETSc users,

    We've always been very conservative in PETSc to keep almost all our
Fortran examples in a format that works with classic FORTRAN 77 constructs:
fixed line format, (72 character limit) and no use of ; to separate
operations on the same line, etc. 

   Is it time to forgo these constructs and use more modern Fortran
conventions in all our examples?

    Any feedback is appreciated

    Barry

Note: it would continue to be possible to use PETSc in the FORTRAN 77 style,
this is just a question about updating the examples.
