Finding Errors Before Generation

You can find errors in the action diagram that would cause generation errors by using the Action Diagram Services panel.

The action diagram editor finds errors such as:

• Missing parameters
• Invalid context
• Invalid domains
• Undefined conditions
• Undefined actions

Note: On the display of errors, you can press F7 to scroll to the next error, and type 3 for the ‘Occurrences to process’ option to scroll to the prior error.

The action diagram editor only finds syntax errors in the current action diagram. It does not find any errors present in embedded internal functions, unless you zoom into those functions first. The action diagram editor does find errors in hidden structures within the same action diagram.

To position to a function or message within an action diagram having a specified source member name or message identifier, respectively, type the implementation name in the ‘Scan for implementation name’ option.

For more information on the Action Diagram Services panel, refer to the Using Action Diagram Services section of the "Modifying Action Diagrams" chapter of Building Applications.

Error analysis capability is also available outside the action diagram as follows:

• The new Check Function Action Diagram (YCHKFUNACT) command processes a list of model objects and produces a listing of functions that contain errors. For functions containing errors, the Option parameter specifies whether to print a report (*PRINT) or load the action diagram of the first function containing an error (*EDIT). The action diagram is positioned at the first block that contains an error.
• Subfile option 38 on the YEDTMDLLST panel scans for errors in the selected function. If any errors are found, the action diagram is loaded and positioned to the first error.
