corral

When a variable has declared lower and upper bounds, if on store, you automatically bring the value into that range, it is called corralling or saturation computing. Corralling makes a special exception for the value 0 which is considered legitimate, even if it is outside the declared legal range. The technique was pioneered in the Abundance language. You could think of it in Java as protecting every store like this:

v = (newValue == 0) ? 0 : Math.Min( Math.Max( v.lower, newValue ), v.upper );

The new MAJC cpus will do these automatically in hardware.
