This paper describes using Authorware Professional, an icon based, object-oriented authoring system, to develop courseware and on- line experiments. Notable features include direct editability, facility with many response types, and built-in variables. Shortcomings include a difficult learning curve, inability to work in msecs., a linear development style, weak drawing tools, a lack of scroll bars for text, and some problems using Authorware with other applications. Overall the package is recommended for users with adequate resources.
