Skip sequential processing varies for RRDS vs. KSDS and insert vs. get. Also position after errors is often different for skip sequential vs. sequential. The intent with skip sequential is to use the sequence set for finding the next key, but of course VSAM has many variations. Those may or may not be relevant to you, but that is probably why the doc is vague on the finer details -- it is environmentally dependent. A big design flaw in VSAM that was made worse each year rather than being rectified, making it too complex to use effectively for most applications.
