Adding Source Code and Building the Project

Once you have created a project, you need to add the source files to it and then compile the project. To add a new file to the project:

  1. Select your project in the Team Developer Tree view and click File > New > COBOL Program .

    This starts the New COBOL Program wizard.

  2. In the New file name field, type tictac.cbl.
  3. Click Finish.

    This creates a new COBOL source file from the default template and opens it in the editor. The file is shown under the project in the Team Developer Tree view.

  4. Copy and paste the following COBOL code into the editor, overwriting the existing text:
          $set ans85 mf align(4) preservecase
           identification division.
               program-id. tictac.

  5. Click File > Save . By default, Eclipse is configured to build projects automatically. If this option has been changed, to manually start a build, select the project in the Team Developer Tree view and click Project > Build Project.
The progress of the project build is displayed in the Console view.

Building the project creates a new folder in your project - New_Configuration.bin. Expand the folder in the Team Developer Tree view to see the executable and the .obj (Windows) or .o (UNIX) files.
