Creating the Project

You will make use of two tools of tool type Execute OS Command from the OS function package:

  • A tool which returns a list of issues filtered by the issue priority.
  • A tool which returns the raiser of a given issue.

You can develop a tool of type Execute OS Command as a local COBOL program to generate an .exe file that can be specified as a tool of type Execute OS Command in the AWM model.

Start by creating a COBOL project:

  1. Launch Visual COBOL. Specify a path for the Eclipse workspace when prompted.

    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 Window > Perspective > Open Perspective > Other, click COBOL (default), and then click OK.
  2. In the Application Explorer view, click File > New > Other.

    This opens the New dialog box.

  3. Click Micro Focus COBOL > COBOL Project.
  4. Click Next.
  5. In the Project name field, type IssueTrackingSystem.
  6. Click Finish.
    Tip: If your project is not visible in the Application Explorer view, right-click Visual COBOL Projects, and then click Load Application.

You now need to create the two COBOL programs:

  1. In the Application Explorer view, right-click the IssueTrackingSystem project.
  2. Click New > File > COBOL Program.

    This opens the New COBOL Program dialog box.

  3. In the New file name field, type GetIssues.cbl
  4. Click Finish.

    This opens the program in the COBOL editor.

  5. Copy and paste the following COBOL code into the editor, overwriting the existing text:
           program-id. GetIssues as "GetIssues".

          * The program reads the issues from the sample data set and      *
