Thanks! That gave me enough to look through the NEWT/0 code and I have
a rough idea of what the above means and see that the arguments do, in
fact, make it that far.

I see the references to NSSYM0(_ARGV_) on the C side, so how does it
become NSSYM(VArgs) or NSSYM(GetVArgs) on the NewtonScript side? Is
there a translation somewhere that I missed or am I misunderstanding?

Thanks again,

Morgan
