GREENPRINT: A graphic representation of structured programs

by L. A. Belady, C. J. Evangelisti, L. R. Power
To improve the readability of programs over existing techniques, a new program representation termed GREENPRINT has been developed and is discussed in this paper. GREENPRINTs (the name taken from the phosphor fluorescence of certain display terminals and paralleling the term blueprints) are tree-structured diagrams together with source code statements that represent the control structure of programs. Discussed in this paper are the diagramming conventions, control flow methodology, presentation graphics, and practical experience with GREENPRINTs.
