The author of pdld believes that the LL on page 193 of this: https://www.ibm.com/docs/en/SSLTBW_3.1.0/pdf/ieab200_v3r1.pdf
if set to 0, means 8. Even though it isn't documented. I think he might have seen that in the object code produced by z390 and assumed that load modules were done the same way. BFN. Paul.
