PROSE modeling language (original) (raw)

PROSE was the mathematical 4GL virtual machine that established the holistic modeling paradigm known as Synthetic Calculus (AKA MetaCalculus). A successor to the SLANG/CUE simulation and optimization language developed at TRW Systems, it was introduced in 1974 on Control Data supercomputers. It was the first commercial language to employ automatic differentiation (AD), which was optimized to loop in the instruction-stack of the CDC 6600 CPU. Although PROSE was a rich block-structured procedural language, its focus was the blending of simultaneous-variable mathematical systems such as:
