In this tutorial you perform the steps typically required in managing, maintaining and running JCL applications. In summary, you:
- Create and configure an Enterprise Server to run JCL applications.
- Create a native COBOL project comprising all the parts of your application, such as the COBOL source programs and a JCL batch file.
- Associate the project with your Enterprise Server.
- Build the COBOL project in your IDE.
- Submit the JCL file to your Enterprise Server.
The JCL performs the following actions on the Enterprise Server:
- Uses the IDCAMS utility to delete any previous instance of the data set that will be created.
- Runs a simple COBOL program (JCLCREAT.cbl) that creates and populates a simple data set.
- Uses the IEBGENER utility to populate a temporary data set.
- Runs a simple COBOL program (JCLREAD.cbl) to write the contents of the temporary data set to SYSOUT.
- View the spool and the catalog to view the results of the JCL that ran.
- Dynamically debug the project.
