In order for today’s modern companies to remain competitive, production systems must be highly available and reliable. The Job Control Language (JCL) is an essential component for the smooth operation of the systems. Errors in JCL coding can adversely affect production and cause unwanted delays.
The challenge: Due to its complexity, the potential for errors is high every time new or modified JCLs are introduced. Under deadline and time pressure, it is not always possible to thoroughly test the JCL for all events before the applications are put into production.
