Suppose I have two identical DSNs on different volumes.
One is catalogued; the other not. (Does SMS allow that
nowadays?)
In a job step I allocate
DD DISP=(SHR,PASS),VOL=SER=<uncatalogued>...
In a subsequent step, I allocate by DSN with no explicit
volume informarion. Which one wins, the passed or the
catalogued?
Where is this clearly documented? I don't see t in
<https://www.ibm.com/docs/en/zos/3.1.0?topic=parameter-passing-data-set>
How would a novice suss this out without a priori knowledge?
What would ChatGPT say?
