  1. CHARTfor Natural Presented by Treehouse Software, Inc. Take a good look at your system ... with CHART

  2. A program structure chart ... HISPROG1 ________| | | CallNat Fetch HERSUBP1 HISPROG2 |________ | | Fetch InputMap HERPROGA HERMAPA | * CallNat HERSUBP1

  3. Overview of this presentation ... What does CHART do ... When to use CHART ... Why use CHART ... Parameters for CHART-ing ... Symbols used in CHART ... How to get CHART-ed ...

  4. What does CHART do ... • draws program calling structures, using source code • all other objects detected are drawn in an easy-to-read format - a CHART • exclude object types from the CHART • "suppress" objects from "expansion" • can be used on-line or in batch

  5. When to use CHART ... • during and after application development • before, during, and after maintenance work on a suite • to permanently document all or part of an application • to audit your application system

  6. Why use CHART ... • "a picture tells a thousand words" • we need structure charts during analysis, specification, development, and maintenance • you can "tailor" a CHART to your particular needs (with “exclusions”, “don’t explodes”) • CHART detects most ways of"dynamically" calling an object

  7.

  9. Why use CHART ... Document and Audit your whole application ... • pass all the “seeds” of your application to CHART (in a work file) • program charts will be printed for each seed • a table of contents will be printed • an index of objects will be printed • an audit list of objects not referencedwill be printed

  10. Invoking CHART On-line ... • At the "Command" prompt: Enter Code: Type: Name:Command: CH PROG1 • or at the “NEXT” prompt:NEXT chart LIB=CHARTV2

  18. Don’t Explode/Show in CHART ... Don't Explode/Show .. MJ*_____ • objects starting with ‘MJ’ will have descendant objects suppressed Don't Explode/Show .. ^MJ*____ • objects starting with ‘MJ’ will not be shown in the CHART at all

  25. Paging around CHARTs on-line ... Page: 1L of 2 left side of first page being displayed 1L 1R 2L 2R Use PF7, PF8, PF10, and PF11 to scroll around on-line: --PF5---PF6---PF7---PF8---PF9---PF10--PF11-- Find Chart UpDown Lines Left Right

  26. Objects with over 15 descendants ... Descendants are split over as many rows as necessary:

  27. Running CHART in Batch ... JCL to runCHART formany seeds(in work file): Extra CHARTsare drawnautomatically(whenevernecessary)

  28. How to get CHART-ed ... • Free trial of CHART at your site • Can be purchased short term or long term • Includes installation, training sessions, reference manuals, and version upgrades • CHART can be “tailored” to suit special documentation needs your site may have
