Thanks.
For what it is worth in regards to question (1), GNU Fortran (Homebrew
GCC 11.3.0_2) 11.3.0 seems to need .F90 (as opposed to just .F).

Two questions about the PetscCall( ) etc. functionality in fortran:
(1) To use this functionality, is it required to use a .F90 naming convention?
or should I be able to use .F?
This likely depends on the compiler.
(2) Is it permitted to use line continuation within these calls? For example
something like
PetscCallMPIA(MPI_Allreduce(localval,globalsum,1,&
MPIU_REAL,MPIU_SUM, PETSC_COMM_WORLD,ierr))
or is it required to just have an extra long line? or is there an alternate
syntax for continuation in this case?
Because PetscCallXXX() is a macro, it "breaks" if a continuation is used,
so yes, you will sometimes need long lines. Most Fortran compilers have an option to
allow infinitely long lines.
Note that you can still use CHKERRQ() either all the time or in situations where you
"need" a continuation character.
