command line option "-sub_pc_factor_levels 1" does not work in fortran

Hi,

I want to change the ilu levels for block jacobi method. What is the 
command line option for it? Or should I use "PCFactorSetLevels" in the 
code? The "-sub_pc_factor_levels 1" does not work in fortran. Thanks.

Bests,
Hui
