Abstract

A solution is offered to some fundamental problems that have thwarted previous efforts to develop a standard command language. The technical approach is based on the form of modularity provided by data abstraction, and this is introduced from the point of view of the end user, together with a discussion of the advantages and disadvantages that might be perceived at this level. This leads to the statement of a simple but stringent set of criteria for the inclusion of functional capabilities in a standard command language and the testing of various candidates against them. Some candidates are accepted and others rejected, resulting in an initial proposal for the scope of a standard command language that is small and simple enough to have a hope of success.
