Question about LET score on carbon

Dear FLUKA experts
When I score the LET follow the topic Scoring both LETd and LETt of primary protons in water,I can get the same results. I want to konw how to score the LET on water for the carbon Ion. Becase I am Be unfamiliar with Fortran, so can you tell me how to edit the fluscw_proton.f.
