In a mainframe environment, you need to create a JCL job that runs a program only if a specific dataset exists; otherwise, it should skip that step. How would you accomplish this using IF-THEN-ELSE conditions?
- Use IDCAMS utility with LISTCAT command to check the dataset existence and IF-THEN-ELSE condition based on the result.
- Use IF-THEN-ELSE condition directly on the EXEC statement with a dataset check.
- Use JCL COND parameter with a condition to check dataset existence.
- Use system utility IEFBR14 to create a dummy step and check for dataset existence.
Using IDCAMS LISTCAT to verify dataset existence and incorporating an IF-THEN-ELSE condition is a common approach in JCL.
