Description of SM

SM is an interactive plotting programme with a flexible command language. The plot data may be defined to SM in a number of ways. There is also a powerful mechanism for defining and editing plot `macros' (sets of SM plot commands that are defined and invoked as plot "subprogrammes").

The features of SM are described fully in the next few sections, but let us start with a description of how to produce your first SM plot. Before you start, notice that SM is case sensitive. Keywords may be typed in lower or uppercase (as we do in this manual), but we would recommend using lowercase. It is in fact possible to change the meanings of lowercase keywords, but this can be confusing. If you are interested, see the section on "overloading". See `uppercase' in the index if you really want to use your shift key.
