Ewart Shaw wrote about these, so look for his emails on the subject
failing other channels. He might like to comment for himself, of
course, if his e-address (as I have it, above) is still correct.

Just one empty stub remains in the Accessible Dictionary (aka NuVoc
--remember it?):
H. (Hypergeometric) Conjunction
http://www.jsoftware.com/jwiki/Vocabulary/hcapdot
Once that's filled-in, then NuVoc is more-or-less ready to go. You can
already see it at http://www.jsoftware.com/jwiki/Vocabulary
But alas, I need help...
The J Dictionary (the old one) references Abramowitz and Stegun (A&S),
Chapter 15: Hypergeometric Functions. Now A&S represent the syntax of the
general case like so:
F(a; b; c; z)
Both NuVoc and the J Dictionary present the syntax of the (H.) primitive
like so:
(m H. n) y
where both m and n are numeric lists.
Now suppose I'm a newbie, and my first sight of:
http://www.jsoftware.com/help/dictionary/dhcapdot.htm
just gives me a dull ache between the eyes. I need clear, unambiguous
instructions for taking any example I choose from A&S and mapping it onto:
(m H. n)y
Let me make a start:
z --> y
That was the easy bit. Now... how should (a; b; c) --> (m; n)?
Or should I be asking: how *best* should (a; b; c) be mapped onto m and n?
Because as I see it, it's ambiguous. Just for starters:
F(a; b; c; z) = F(b; a; c; z) -----[A&S 15.1.1]
Suggestions please.
