Abstract :
VIFOR is a software tool for maintenance of large Fortran programs. The distinguishing feature of VIFOR layouts is the placement of all nodes into two columns depending on their class, which is referred to as a two-column graph (2CG). The 2CG consists of two subgraphs, the call graph and the reference graph. The algorithm proposed first builds the call graph by determining the positions of the nodes in the process column, and then it appends the reference graph to the drawing. The part of the algorithm that builds the layout of the call graph is described. The algorithm tries to communicate as much information about the call graph as possible. The space optimization is considered to be secondary
