Job Information Language (about jil script)

• JIL is a specification language. 
• It has its own syntax.
• It is used to describe when, where and how job should run.
• When you enter the jil command, you get the jil command prompt, at which you can enter the job definitions one line at a time using this special language.
• In this case, When you exit the jil command-line interface, the job definition is loaded into the database.
• Alternatively, you can enter the definition as a text file and redirect the file to the jil command.
• In this case, the jil command activates the language processor, interprets the information in the text file, and loads this information in the database.
