//********* BenchPress-v3.js **********
//
// A set of benchmarks to measure the efficiency of language implementations.
// Based in part on the Stanford Integer Benchmarks originally written by
// John Hennesey, modified by Peter Nye, and further modified by members of
// the Self group under David Ungar and Randy Smith.
//
// To be consistent with other languages, some benchmarks use 1-based indexing.
// To support this, arrays are created with an extra element and the contents
// of their zeroth entries are ignored.
//
//
// John Maloney, August 1995
