If you need values orders of magnitude bigger than the defaults, something is
drastically wrong. First, you need to look at the output and see which
parameter it is that is too big (compare your output to line 82 or thereabouts
of rdparm.f). And then you should try to figure out what there is about
your system that is making the required numbers so big--even a very large
protein only has a limited number of types of bonds, etc.

If you do change the code, the limits are in parms.h as well as in rdparm.f.
