A continuous-system simulation language designed for LSI economics

As computing hardware gets cheaper, and labor gets more expensive, the economics of developing relatively limited distribution software such as continuous-system simulation languages for minicomputers (compared to Fortrans and other system software) changes. A philosophy of low-cost software is propounded here, and an example of a language adhering to that philosophy is presented. It is an equation-oriented language capable of solving differential or difference equations. It runs completely in memory (requires no mass storage device). Examples of its use are given, including a PHYSBE solution.
