NOT CATLGD 2 JCL Error-How to Avoid it?

The NOT CATLGD 2 JCL Error mostly occurs, when the dataset in question already exists. Here, OUTFILE is trying to create a new dataset OUTFILE.TEST.DATA. So, probably this dataset already pre-exists and is cataloged. To ensure such errors don’t occurs, we must purge/delete datasets using IEFBR14.
