A hybrid implementation of a process‐oriented programming language for system simulation

摘要

AbstractThe implementation of a hierarchical, process‐oriented programming language for simulation (HSL) is described. It features a hybrid approach, involving the front end of a compiler and the back end of an interpreter. An HSL program is dichotomous in structure. Source statements from each part are translated into three‐address code for an abstract machine, and the resulting code is then interpreted. The algorithms and the supportive data structures that effect the translation and interpretation of HSL are detailed. The host language for HSL is C++. HSL is machine independent and can be ported to any machine on which the host language is available. Its initial implementation was carried out on an NCR Tower. More recently, it was transferred to an NCR PC
