You can set any of the debug flags (debug(1)-debug(5)) to one in order to have SIMC dump very large amount of information about each event. The comments give an IDEA of what type of information gets dumped.
debug(1) = 0 ; turns on output from brem.f debug(2) = 0 ; into/outa subs debug(3) = 0 ; spit out values (init. and main loop). debug(4) = 0 ; mostly comp_ev, gen_rad diagnostics. debug(5) = 0 ; a bit of everything
