Your first job: back up a dataset
Before tonight's payment run, your team lead asks you to keep a backup of the payment input file. The job COPYJOB in LEARNER.JCL is meant to copy LEARNER.PAY.INPUT to LEARNER.PAY.BACKUP with IEBGENER, but nobody has run it yet.
What you will do
- Submit a job and read its output
- Fix a DD statement
- Check the copy in the dataset browser
