Abstract

This article describes a method used in a greenprint display program which can display an entire structured program, or its segments of interest to the programmer, on a graphic storage device attached to an IBM 3277 Graphics Attachment and Programming RPQ #P090l3. The greenprint generator described in the IBM Systems Journal, Vol. l9, No. 4, l980, produces a graphical representation of a structured program in hard copy output format. This display program enables: (Image Omitted) 1. A compressed version of the entire structured program to be displayed to aid inspections, walkthroughs, and assessments of program nesting. 2.

Greenprint Display Program

This article describes a method used in a greenprint display program which can display an entire structured program, or its segments of interest to the programmer, on a graphic storage device attached to an IBM 3277 Graphics Attachment and Programming RPQ #P090l3. The greenprint generator described in the IBM Systems Journal, Vol. l9, No. 4, l980, produces a graphical representation of a structured program in hard copy output format. This display program enables:

(Image Omitted)

1. A compressed version of the entire structured program to be displayed to aid inspections,

walkthroughs, and assessments of program nesting. 2. Text associated with greenprint control structures can be moved in or out of the depiction

of control structures, giving the programmer a

choice between density and compre hensibility. 3. There is no arbitrary limit to the depth of nested structures displayed, because of the

display program's windowing capability.

4. Greenprints can be produced and analyzed without

the delay associated with hard copy turnaround, or

the graphical limits imposed by the capabilities

of printers and/or 3277's. 5. Graphical output is dynamically justified to the dimensions of the graphical display screen,

depending on the segment of the Greenprint covered

by the window. Fig. l shows the method used by this display program, and Fig. 2 shows an example of a display of a particular program.
