Command language vs. Menüs or Both ?
(Software-Erqonomie '85: Mensch-Computer-lnteraktion, 1985) Stelovsky, Jan; Sugaya, H.
Command languages have been widely used to describe the interaction between man and Computer. Their syntax permits the expression of complex commands, but is considered a hindrance when it must be rembered. An alternative technique, menus and selection by pointing, has gained acceptance among users of interactive Systems. Recently, this method has been further ref ined: icons and Windows help represent and select data as well as command objects. This paper describes a hybrid approach realized in the experimental System XS-2. In XS-2, the command language is combined with the menu selection by pointing, thus merging the expressive power of the former with the simplicity of the latter. In particular, the syntax of the command language is displayed and guides the user during the command input.
