Hello Bruce,

i opened the one big feff84.f file and searched for "nclusx=175" and
changed this to "nclusx=300" in the whole file. Then i compiled it with
f77 -o and so on. I started my feff-run and it seems to be good. Is this
proceeding wise? I don't know much about such things :-/

Thanks for your help and time.
