   ACSL(the Advanced Continuous Simulation Language) can be used to solve 
single or systems of linear or nonlinear differential equations in a very
conversational manner.  Any kind of block diagram lends itself well to the
language use. There are transfer functions, various forcing functions,  7 or
more different integration schemes, vector integrators, MACRO's, etc., all in
very conversational form.  FORTRAN is a subset of ACSL.  Programs can be run
interactively with plots comi ng up in a pop-up window.  Discrete events are 
easily added to the continuous model.  All frequency domain plots are also 
available.
