An effective preprocessor for structured FORTRAN: The HENTRAN system

In the paper the new HENTRAN preprocessor for structured FORTRAN is illustrated. The motivations and the goals of the project are first outlined. The extended FORTRAN language implemented through HENTRAN is then illustrated and its adequacy and flexibility for structured programming are discussed. The basic architecture of the HENTRAN translator is described and its main features concerning reliability, portability, and efficiency are discussed in comparison with other similar systems.
