fortran 90 program with PETSc

[tsjb00]

compiling passed if:
     use parm
      implicit real*8 (a-h,o-z)
#include "finclude/petsc.h"

Is this ok? Many thanks!

Many thanks for your help! I've tried the method in your email .
In the main program called driver.F, it is coded:
      program main
      use parm
#include "finclude/petsc.h"
      implicit real*8 (a-h,o-z)
.................................
I got the following error information :

 In file driver.F:280

      implicit none                                                     
                                                                       1
 In file /home/jinbei/Soft/petsc-3.0.0-p5/include/finclude/petsc.h:209

     Included at driver.F:279

                    
                   2
Error: IMPLICIT NONE statement at (1) cannot follow data declaration statement at (2)

Would you please tell me what might be wrong?

Many thanks in advance!
