Improved human engineering can add significantly to the acceptance and use of computer technology. We report here an experiment in which users with varying degrees of interactive computing experience used two versions of an interactive text editor: one with an English-like command syntax, the other with a more notational syntax. User performance differences strongly favored the English-like editor at all levels of experience.
