OSIPE - A TOOL FOR SCIENTIFIC PROGRAMMING IN FORTRAN

FORTRAN tools have been designed to support well-structured, modular, route-independent and easily interfaceable programming. This set of to ols, which creates a kind of low-level object-oriented programming env ironment, is refered to as OSIPE (Open Structured Interfaceable Progra mming Environment). Its main role is to transform meaningful FORTRAN v ariables into Objects which are linked via ''created-by'' relationship s. Two programs, written in the OSIPE environment, an ab initio electr onic structure code, MUNGAUSS, and a novel implementation of a quantum chemical solvent effect theory, SOLVENT, are briefly described. Effic ient tools are provided to restructure existing FORTRAN codes and make them compatible with the OSIPE environment.
