Programming in *.f90 free format with PETSc

[Ben Tay]

Thank you Satish. I followed what you recommended exactly and used

sed -e 's/^C/\!/g'

With the new mpif.h, I got the following error:

global.i90
d:\cygwin\codes\MPICH\SDK\include\mpif.h(174) : Error: DEC$ ATTRIBUTES 
DLLIMPORT attribute can appear only in an interface-body.   [MPIPRIV]
!DEC$ ATTRIBUTES DLLIMPORT :: /MPIPRIV/

It points to this error in mpif.h

! Intel compiler import specification
!MS$ATTRIBUTES DLLIMPORT :: /MPIPRIV/
! Visual Fortran import specification
!DEC$ ATTRIBUTES DLLIMPORT :: /MPIPRIV/            -   in here
      COMMON /MPIPRIV/ MPI_BOTTOM,MPI_STATUS_IGNORE,MPI_STATUSES_IGNORE
      PARAMETER (MPI_MAX=100,MPI_MIN=101,MPI_SUM=102,MPI_PROD=103)
      PARAMETER (MPI_LAND=104,MPI_BAND=105,MPI_LOR=106,MPI_BOR=107)

Hope you can help again. Thank you very much.
