QUESTION: Where do we find out how to access some thing bigger then a real or double >> 10**40? We both learned .FOR on DEC-10 and VAX/VMS and got spoiled by documentation. My wife is a Nuclear Engineering student whose programs won't run under unix(SYS V), the errors are floating point overflow- she has variables hit magnitudes of 10**250! We borrowed a friends ibm pc compatible and Digital Research's Fortran-77 compiler and the program ran(and ran and ran-almost 2 hours). The catalog from AT&T Customer Information Center didn't provide much help. We're under Sys V on a VAX-780. I don't normally read net.lang so please email. I'll honor requests to summerize if there are any.

You could always get a PDP-8, with its 2^(2^11) ~ 10^600 floating-point
range. If you could find the floating-point hardware processor that
went with it, you would really have a pretty good system.
