You will make use of two tools of tool type Execute OS Command from the OS function package:
You can develop a tool of type Execute OS Command as a local COBOL program to generate an executable file that can be specified as a tool of type Execute OS Command in the AWM model.
Start by creating a COBOL project:
If this is the first time you start Eclipse, the IDE displays the Eclipse Welcome page. Click Open COBOL Perspective which is the default perspective in Visual COBOL.
If the IDE does not start in the COBOL perspective, click , click COBOL (default), and then click OK.This opens the New dialog box.
You now need to create the two COBOL programs:
This opens the New COBOL Program dialog box.
This opens the program in the COBOL editor.

* Results view. *
* The program allows to filter the issues by the input parameter *
