CA JCLCheck Workload Automation includes the JCLNeat feature that allows a standardized format of JCL in your environment.
With Jclneat you can reorder keywords JCL, make single or multiple keywords present on JCL statements, do mass change of the JCL in a partitioned dataset or just specific members.
Change to be done in JCLs can be specified using different methods depending on the complexity of the change that needs to be accomplished, using either specific DD cards or a REXX procedure for the most complex changes.
Jclcneat can be run either in batch or online through standard ISPF panels.
Please review the CA JCLCheck Workload Automation Command Reference Guide and Technical Document TEC1116565 for detailed examples
