Some of your existing started tasks may offer you greater benefits if the source JCL were a job. Review existing started tasks and identify the ones that should be a job by comparing their needs with the support provided (for example, output or accounting).

When you have identified that the source JCL will be a job, determine which method you will use to convert existing procedures, and determine whether the system services that the started task will require have changed. (See Determining system services for a started task.)
