      Notes:    Turbo Basic's register buffer is loaded into the
                processor's registers just before the interrupt is invoked
                and is restored immediately after the interrupt finishes.
                Registers may be set and read via the REG statement and
                REG function.

                The register buffer does not store DS, BP, SS, and SP. The
                programmer is responsible for preserving these registers.
