Abstract: When developing software for certain well-known special functions, and allowing large values of parameters, efficient methods can be based on uniform Airy-type asymptotic expansions. Examples are the modified Bessel function of purely imaginary order and parabolic cylinder functions. We discuss new codes for these functions and for Airy functions in the complex plane. As a spin off, software for Scorer functions (inhomogeneous Airy functions) and properties of their zeros will be considered. This research is done together with Amparo Gil and Javier Segura (Madrid, Spain).
