RE: QUSRSPLA and operating system upgrade

>Does anyone have a good example of using QUSRSPLA

The key is in understanding that the data structures can always shrink/grow
- even a PTF can cause this, not just an OS upgrade.  So when designing the
'fetch data' loop, you fetch the size of your data structure, but you offset
to the next structure by the returned size.

fetch_len = sizeof(QUSH0100)
call QUSRTVUS (space: position: fetch_len: DS: error)
position = position + QUSOHS

Hope that helps
