Create a PL/I source file, opdemo.pli

  1. Right-click the project in the Team Developer Tree view and select New > File > PLI Program.
  2. In the New file name field, enter opdemo.pli. Click Finish. The editor appears with skeleton code for opdemo.pli.
  3. Overwrite the skeleton contents with the following code:
     OPDEMO: PROC(JCLPARM) OPTIONS(MAIN) REORDER;
     
     
     DCL JCLPARM CHAR(20) VARYING;

  4. Save the file.

By default, saving a file automatically triggers a build of the project. You can see the progress of the build process in Eclipse's Console view.
