REDUCE--code to calculate differential invariants of hyperbolic Monge-Ampere equations,

In this paper, the code of the computer algebraic system REDUCE to calculate differential 
invariants of generic hyperbolic Monge\-/Amp\`ere equations is represented. This code 
realizes the algorithms of calculations of these invariants obtained in the paper
