sorry, I think we need no comment and just admire the genius here :
++ HOLD(UI63392) SYSTEM DATE(19154) FMID(HDBBB10)
With the application of the PTF for PH08983, a change of behavior will occur in the following situation:
LOAD specifying PARALLEL with a single input data set and having discarding active with the discard data set defined
with a TEMPLATE.
Previous to this APAR, the discard data set in the above scenario would not have been allocated if there were no rows
to be discarded. Now with this fix, the discard data set will be allocated whether there are rows being discarded or not.).
