Direct execution of C-string compiler texts

Abstract

High level language (HLL) computer architectures refer to those computers which are designed to accept either HLL source texts directly or intermediate texts preprocessed and prepared by HLL compilers. This paper investigates the direct execution of three C-string formats: duos, triples, and quadruples. Software simulators are developed which directly execute these C-string formats on an IBM 3033 architecture. The simulators are then executed for each of the C-string formats, testing the efficiency of each directly executed language (DEL) format for various workloads, on different mainframe architectures, and for five different HLL's. The results demonstrate that triples are the most efficient DEL format in support of most HLL texts on large-scale mainframes.
