|17bii/19bii utpn awol|

i had expected implementing black scholes using the 17bii/19bii's powerful solver would be easy.
nope. utpn (upper tail probability normal) is missing. theres a cheesy version of bs in the hp support docs, but it uses a 4 term hastings approx of the normal distribution (|e| < 2.5e-4). so it doesnt even get 4 figs.
i wonder why they didnt put it in.

does anyone know if there's some way (eg using let & get) to make a subroutine?
