(1) What is the (A & S or G & R) name of the %P function in
(%i5) hgfred([a+1/2,a],[c],x);
(%o5)
(2^(1-c)*%P[2*a-c,1-c](1/sqrt(1-x))*(1-x)^(c-2*a-1/2)*x^(-2*c+2*a+1))/(gamma(c)*(x^2-1)^((1-c)/2))
(2) Where can I find a reference to the identity %i5 = %o5 ?
(3) Does the message 'simp2f1-will-continue-in' have any meaning
that a user should know about? For example
(%i6) hgfred([a+1/3,a],[c],x);
SIMP2F1-WILL-CONTINUE-IN
(%o6) %F[2,1]([a+1/3,a],[c],x)
