First, understand why you're getting the numeric overflow,
and then fix the bugs.

If your programs were working fine before, look for
alternative ways of doing what what you want.  For most
uses of truncation on arithmetic operations, there is an
alternative that's better.  If you can describe what types
of operations are being done, we can help suggest
alternatives.

The easy way is to keep doing arithmetic using the
traditional fixed-format opcodes for those operations
that overflow.
