In MicroWorlds 2.0, the transparent color was 0 (zero). You could use it in a
shape, if you wanted shapes to be partly see through. Or you could use it to
"erase" part of a drawing. I'm sure there are other uses as well. I used to
show my students how I could make a ghost partly see through. In MicroWorlds
EX, I assumed that if I set the opacity using the setopacity word or using the
slider in the paint tools, I would have the same effect. I've used various
versions of Logo since 1982, but this is my first few months with EX, so I'm
just learning again.
