CHART for NATURAL assists with the analysis and documentation of NATURAL applications. CHART draws the object-to-object calling structure of any NATURAL application in an easy-to-read graphical format. CHART can be used on-line or in batch, and gives fast accurate results. CHART is a well-rounded and friendly tool for analysts and programmers. CHART reads the source code of your application (across your normal step libraries), builds an object-to-object calling structure, and presents the results. From this point, you can browse any object without leaving the chart or the chart can be re-drawn using different criteria.
