I probably should, but see below. (And thanks for the drs-to-ps script, 
which I will study and adapt.)

My first assignment also uses images (and Kathi's fabric teachpack). But 
it's still not necessary to cut them out of the Interactions window and 
paste them into Definitions, and in any case I am not talking about 
images. I am talking about numerical results. I ask them to do something 
like compute taxes in a multi-bracket system, and they create their 
examples and tests by running their code, getting numbers in 
Definitions, cutting them out, and pasting them into an example-comment 
or a Boolean test expression. Except taxes have decimal places, 
typically, and what they paste is not a piece of simple text, but a 
snip. What is the utility of permitting a student to cut a snip 
representing a rational, as opposed to a textual representation of a 
number, out of the Interactions window?

That's okay. Given the pressures on us, and the weaknesses of this 
medium, we all get a little, er, snippy at times. --PR
