Abstract

This paper describes a newly designed programming language, FORMAL-2, and its processing system. The main features of FORMAL-2 are: (1) FORMAL-2 is data-type free, i. e. , data-types and operations over them are left unspecified in the kernel of the language. (2) Every procedure is declared and identified by its ″form″ , hence FORMAL-2 programs would be highly readable. (3) The nondeterministic expression proposed by R. W. Floyd may be used in an extended style. FORMAL-2 processor is implemented on the minicomputer PDP 11/20 with comparative ease. The processor is compact and small, and consists of a data-type free part (MONITOR, COMPILER, EXECUTOR) and a data-type dependent part (STANDARD - REPERTOIRE). The extensibility of the language is realized by the file facilities.
