Rather than the not_used subfield, I think it's better explicitly code a
length of 100 on the DS to avoid defining too many/too big subfields,
and overrunning the length of the scratchpad.

 d ScratchPad      ds           100     qualified based(ptrScrPad)
 d  len                          10i 0
 d  countr                       10i 0

Ack, I just noticed that you provided an example of the problem by
coding not_used as 96a instead of 92a.  If you did a CLEAR ScratchPad,
it would overrun the real SCRATCHPAD by 4 bytes.
