List several situations when command languages can be attractive for users.
What will be an ideal response?
Command languages can be attractive when frequent use of a system is anticipated, users are knowledgeable about the task and interface concepts, screen space is at a premium (e.g. Smartphones), response times and display rates are slow, and numerous functions can be combined in compact expressions (e.g. point-of-sale terminals). Users have to learn the semantics and syntax, but they can initiate, rather than just respond, and can rapidly specify actions involving several objects and options. Finally, a complex sequence of commands can easily be specified and stored for future use as a macro.
