Not if _BPX_SHAREAS=YES. If a process is created in a separate address
space then it is in a separate jobstep.

I don't understand the question. The Unix process gets control with
whatever stdin and stdout the caller specifies. It doesn't and
shouldn't allocate anything as long as stdin and stdout are all it
wants. Those names refer to pre-opened files, not to ddnames.
Think of stdin, stdout and stderr as being open DCB's passed to the
process. It's not a perfect analogy, but it conveys the flavor.
