Visual support for programming-in-the-large

Abstract

In this paper, a brief description of the VIFOR (Visual Interactive FORtran) environment is given. VIFOR is based on a simple, but effective data model of Fortran programs. The model contains three entity classes and three relation classes only. Programs can be displayed and edited in two forms: the traditional one (i.e. code) and in the visual form. VIFOR contains transformation tools for both directions, i.e. from code to visual form and from visual form to skeletons of code. Hence, it is suitable for reverse engineering and maintenance of existing code. Specially designed browsers implement the graphical interface.

Dynamic Analysis of Test and Evaluation Software

“…A tool for modeling large FORTRAN programs was described by Rajlich, Damaskinos, Linos, and Silva (1988). The VIFOR tool displays a graphical representation of the FORTRAN code in order to enhance understanding and to aid in building and modifying the program.…”

“…An interactive tool for C is being developed at Wayne State University, but no FORTRAN tool was available for this study. In the absence of such a tool, the VIFORtool (Rajlich, Damaskinos, Linos, and Silva, 1988) was used. VIFOR parses FORTRAN 77 code and creates a database of program entities and modules and of the relationships between them.…”

Program view generation and change analysis using attributed dependency graphs

“…et al, 1990;Chen, S . et al, 1990;Collofello and Orn, 1988;Heisler et al, 1993;Linton, 1984;Rajlich et al, 1988;Yau and Tsai, 1987). A program information base contains key relationships between components of a system and is usually obtained by parsing the program.…”

A combined representation for the maintenance of C programs

“…Rajlich et al [74] describe a maintenance environment for Fortran, VIFOR (Visually Interactive Fortran). The tool provides a visual form for Fortran programs in addition to the source code.…”
