Answer 1

elaborating on my comment, here is a python example:

 fortrancode = """
       implicit none
       integer, parameter :: n=%i
       integer,parameter :: rp=selected_real_kind(n)      
       write(*,*)n,rp
       end
 """
 from subprocess import call
 for n in range(-1,33):
  f=open('test.f','w')
  f.write(fortrancode%(n))  ! <- n here gets string substituted
                            !for the '%i' in fortrancode
  f.close()
   ! optional check  call(['grep','n=','test.f'])
  call(['gfortran','test.f','-o','test.exe'])
  call(['./test.exe'])

python test.py
