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).
