It's also at least theoretically possible for one jobstep to create a load
module that is executed in a subsequent step - so a "verification" of the
latter step without executing the former will fail - but the job would not
fail in actual execution.

Didn't some early report writer type products work this way? Build COBOL
source code for a compile, link, and go?

Hmmm..    Is this a test?  Game playing?
