You are laboring under two falsehoods.
As written here, it does not matter if MY.DS exists before the job is run. See the discussion of DISP=MOD in the JCL Reference manual for your z/OS release.
The JCL in S2 does not specify RLSE. That's because RLSE is not a data set attribute; it only applies to the step and DD statement that populates the data set; S2 does not populate the data set.

You are laboring under two falsehoods.
- IEFBR14 always terminates with RC = 0. There is no concept of âno return code.â All programs end with a return code.
- This JCL will fail if the system cannot allocate or delete MY.DS.
