Hi,
you can include the subroutine by using the keyword FORTRAN FILE and give the used subroutine. If you like to modify more than one soubroutine, you can copy all your modified subroutines in one fortran file.
To set up the values, you have to modify the fortran file of the subroutine depending on your requirements. You can search the forum after the BORD subroutine to get an idea what to do and you will have to go through the file and check what you have to change.
Hope this helps a litte bit,
Regards
