Ultra-fast hybrid analog-digital computations with convenient simulation-language software

The succession of digital program steps in typical hybrid analog-digital computer simulations is so similar to the stepwise solution of differential, equation systems that well-established continuous-system-simulation languages, and especially interactive digital simulation systems, can serve as excellent hybrid-computer software; with little modification. In particular, the block-diagram-oriented DARE II simulation language can control the ultra-fast LOCUST analog computer to produce unprecedented hybrid execution speed while still permitting quite simple programming. Examples include iterative optimization, computation of hybrid-computer Monte Carlo statistics and digital two-variable function generation in a hybrid-computer loop.
