Whoops! I guess I should have tested that code. I was
distracted by the plumber telling me know what the problem
is in the bathroom. Let's just say the era of free advice
may be a thing of the past. :-(

Try this:

sphere = FltArr(40, 40, 40)
FOR x=0,19 DO FOR y=0,19 DO FOR z=0,19 DO $
sphere(x+10, y+10, z+10) = SQRT((x-9.5)^2 + (y-9.5)^2 + (z-9.5)^2)
indices = Where(sphere Lt 9.5 AND sphere NE 0)
sphere(indices) = 255

Cheers,

David
