I am using Coot 0.9.8.95 EL on a Mac.
I wanted to use the dots command to draw a sphere of variable size around an 
atom.
the command :
dots (0,"1","name",1.0, 1.0) does the job
but whatever radii I define, I get the same sphere on the screen.

Is this command really working ? or just not on a mac ?
or ...

I see what you mean. The radius scale is ignored. That is a bit disappointing.

Seeing as you want dots around only one atom, as a workaround you can use

to_generic_object_add_points,

e.g. (off the top of my head)

points = make_points()

o = new_generic_object_number("Sphere of Unusual Size")

to_generic_object_add_points(o, points)

set_display_generic_object(o, 1)


where make_points is a function that returns a list of points on the surface of a sphere, where each point looks something like ["orange", 2, x, y, z], the points being those on the surface of a scaled Fibonacci Sphere (say) displaced by the position of the atom.
