Syntax driven COBOL compilers—an assessment

Most syntax analysis phases of COBOL compilers are written as sequences of procedural code instructions each of which validates a particular part of the syntax of a COBOL program. This paper examines the structure of a syntax driven COBOL compiler and a practical implementation is described. The problems encountered with this type of compiler construction are explained, and its advantages are examined. Finally, some other potential applications of syntax driven technology are suggested.
