Computer software for generating flowchart images of a source program

摘要

Computer software for generating flowchart images of a source program. The computer software includes a first program which reads an input program source code as an input and generates a coded output file containing codes that a second program uses to create the shapes of the flowchart or list the copybooks and called programs used in the input program source code being flowcharted. Each line of the source program input is checked character for character for ‘reserved words’ of the source program language. When a ‘reserved word’ is found then a shape code is created. A single program flowchart can be created or by selecting a key word “AUTO”, multiple program flowcharts can be created. The coded output file contains first, second, and third fields. The first field contains a three character shape identifier (the computer software includes 25 predefined shape identifiers). The second field contains a view number and a shape position. The view number indicates a particular flowchart screen for the program flowchart. The shape position indicates a particular position of a flowchart screen. Each flowchart screen can show up to nine shape positions. The second program of the inventive software reads the coded output file of the first program and displays the program flowchart images screen by screen.
