An algorithm is described for computing the values of the confluent hypergeometric function at several points spaced densely along an interval of real numbers. Numerical data obtained by using this algorithm and pertaining to a commonly made approximation for the first-passage problem of the response amplitude of a lightly damped and randomly excited linear oscillator are presented.
