• the different processes, calls to procedures found in a WLanguage procedure or process. The final graph is called "Graph of callees".
  This type of graph allows you to understand how a procedure is organized and to find where modifications must be performed (when re-using an existing code for example).
• the different processes that call a WLanguage procedure or process. The final graph is called "Graph of callers".
  This type of graph allows you to evaluate the impact of a modification made in a procedure.

Example: modeling of the callees for the "OrderValidation" procedure

1. Process for which the reverse modeling was performed.
2. Process called.
3. Non-detailed group of processes.
4. Detailed group of processes.

In the graph, a group of processes can be detailed or not. The icon is used to expand a group of processes and is used to collapse a group of processes.

1. Start the wizard for reverse modeling:
   • select "Reverse-modeling" from the popup menu of the procedure ("Project explorer" pane).
   • from the code editor. To do so, position the mouse cursor on the name of a procedure, in a process, a procedure, a class code, ... and select "Reverse-modeling" from the popup menu.
   • from the cross-reference window of a procedure (opened by "Shift+F2"): click the "Reverse modeling of callers" button ("Callers" tab) or the "Reverse modeling of callees" ("Callees" tab).
2. Choose the requested type of graph: Graph of callees or Graph of callers.
3. Enter the name of the flexible modeling that will be generated.
   This name has the following format by default: "Reverse modeling of <callees/callers> by <Procedure Name>".
4. Select the options for coloring the modeling. You have the ability to color the processes: in this case, all the processes belonging to the same project element (window, class, ...) will use the same color.
   You also have the ability to enable the alignment grid in the modeling editor.
5. The processes can be grouped by feature.
   We advise you to create groupings when reverse modeling is performed on complex procedures. They provide a synthetic view before exploring the code step by step.
   For smaller processes, we advise you not to create groups in order to directly access the maximum level of details. However, the level of details cannot be modified in the modeling editor.
6. Validate the creation of the graph. The modeling editor is opened and the generated graph is displayed.

Changing the level of details in the modeling

Grouped processes	Detailed processes

• of a process: double-click the icon of the process displayed in the modeling.
• of all processes in the graph: click the icon in the toolbar.

• of a process: double-click the icon of process.
• of all processes in the graph: click the icon in the toolbar.

Accessing the code of a process from the modeling

• double-click the button of process.
• press the "F2" key on the selected process.
