The values in the DCB *are* the dataset attributes.

Then by *your* definition there is an override; the OPEN completes
with RC 0.

What if the job gets an 0C7 because of invalid decimal data? Does that
mean that there was no override?

Are you incapable of accurately citing what others have written? The
important thing to understand about override is how it works.

Yes. What if the user submits a STEPLIB override with a load library,
but not the correct one. Would you claim that there was no override?

Do you consider lying about the positions of your oponents to be a
valid debating tactic?
