Subject:  Question: Handling very large integer values from Fortran
To:       info-vax@sri-kl.arpa
X-Original-To:  info-vax@sri-kl.arpa, JWR8728

    One of our users has a need for performing integer arithmetic on
very large numbers (on the order of 2 ** 300).  Specifically, he needs
functions to add, subract, and compare two numbers of this magnitude, as
well as test individual bits in the result.
    Does anyone know of or perhaps already written a routine to simulate such
a situation?  We have a VAX running VMS 4.5.  The application is written  in
VAX Fortran 4.6.1.
                                Thank you,
