Usually parenthesized superscripts like this refer to derivatives. See, for example, what you obtain when you evaluate D[Hypergeometric1F1[a, b, x], a] The (1, 0, 0) means that the function Hypergeometric1F1 has been differentiated once with respect to the first variable (a) , and zero times with respect to the others (b and x). -- P.J.
