Title: Theory of interpretive architectures: some notes on DEL design and a FORTRAN case study. Technical report No. 171

Technical Report ·
OSTI ID:6130444

An interpretive architecture is a program representation that peculiarly suits a particular high-level language or class of languages. The architecture is a program representation called a directly executed language (DEL). This paper attempts to develop a reasonably comprehensive theory of DEL synthesis. By assuming a flexible interpretation-oriented host machine, synthesis involves three particular areas: sequencing (both between image machine instructions and within the host interpreter) action rules (including both format for transformation and operation invoked), and finally, the name space which includes both name structure and name environment. A complete implementation of a simple version of FORTRAN is described in the appendix of the paper. This DEL for FORTRAN, called DELtran, comes close to achieving the ideal program measures. 10 figures, 5 tables.
