Ok, that looks fine. however, there is a dependency that HNKSZ >=
PGSZ, right? And that is currently hardwired to (4 * PGSZ)?

And given that the intent of the PGSZ was to be made variable at
some point, isn't this really trying to ensure that HNKSZ is always
greater than the PGSZ the program was built with?

Cheers,

Dave.
