HPFADDTOPPOINTER accepts neither a constant nor an expression for the
#bytes ... it takes a 64-bit integer by reference.

I suspect the reason for this is that they wanted it callable from
languages that don't have 64-bit integers.  (In such languages,
you would presumably cobble together a 64-bit variable of some kind
to hold the #bytes.)

What I find harder to understand is why the address of the 64-bit
variable is a 64-bit address!   (Hmmm...a bit of an about face
by someone who once argued that *every* intrinsic reference parameter
should be a 64-bit address! :)
