Abstract : FSCAN is a language for specifying the lexical analysis of programs written in any current programming language, including FORTRAN. This report describes the FSCAN language, a compiler for the language, and an interpreter for the resulting object code. The interpreted object code forms an efficient lexical analyzer that takes as input a stream of characters and produces as output a stream of tokens (lexical units). The compiler and interpreter are designed for portability. Both are written in ANSI FORTRAN supplemented by a small number of short machine dependent subroutines. Included is a FSCAN program describing a FORTRAN-77 lexical analyzer. (Author)
