Contribution

It introduces a novel REC interpreter implemented in FORTRAN, simplifying the process for students to write and understand recursive programs.

Findings

REC language is concise and easy for students to learn

The FORTRAN interpreter effectively executes REC programs

REC's simplicity aids in teaching programming fundamentals

Abstract

REC (Regular Expression Compiler) is a concise programming language which allows students to write programs without knowledge of the complicated syntax of languages like FORTRAN and ALGOL. The language is recursive and contains only four elements for control. This paper describes an interpreter of REC written in FORTRAN.
