function definition of that symbol.  By convention, commands are
named with a com - prefix, although CLIM does not enforce this
convention.  To avoid collisions among command names, each

command com-show-chart would have a command-line name of Show

application's command defining macro), you can have a command
line name generated automatically. As you can see from this
