Need 64 bit integers on VAX

[arny@wayback.UUCP (Arny B. Engelson)]

We are using VAX Ada and need to store 64 bit integer numbers.  Since an
Integer is 32 bits, we have a problem.  For reasons I won't go into,
Floating and Fixed point representations are out.

Is using something like Unsigned_Quadword, and overloading the arithmetic
operators, the way to go?  Has someone already coded these routines?

Any solution has to allow normal arithmetic operations and I/O capabilities.
It has to look and feel, to the user, like an integer.

What solutions have people come up with to this type of problem?
