The call sequence is <A HREF="../Sys/PetscPrintf.html#PetscPrintf">PetscPrintf</A>(<A HREF="../Sys/MPI_Comm.html#MPI_Comm">MPI_Comm</A>, character(*), <A HREF="../Sys/PetscErrorCode.html#PetscErrorCode">PetscErrorCode</A> ierr) from Fortran.
That is, you can only pass a single character string from Fortran.
<P>
Notes: The %A format specifier is special. It assumes an argument of type <A HREF="../Sys/PetscReal.html#PetscReal">PetscReal</A>
and is replaced with %G unless the absolute value is < 1.e-12 when it is replaced
with "< 1.e-12" (1.e-6 for single precision).
