It would be helpful if you could give us a context for the output that you
are describing. 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).
