I don't object to doing this, but I asked about it earlier and got no 
response. My earlier question was this: when I am in DrScheme and choose 
"Print" from the menu, I get a fixed representation printed out (which, 
for the sample code I chose, used too large a font, and the lines 
wrapped around). Can I script this so that it can be done with 200+ 
student submissions, and how much control do I have over the look?

Note that I have a solution which works when student submissions are 
text files, and there's no reason for them not to be text files, given 
the questions I am asking, which at this point do not involve images or 
anything like that. More generally, if I want to post-process student 
submissions in any way, it's usually pretty clear how to do it with a 
text file, and not so clear when it is something more complicated. (I 
have wxme-to-text, Eli, thank you. This is what my TAs are using when 
they discover a problem.)

Finally, I just don't understand why beginning students (as opposed to 
experienced Scheme programmers) would need the ability to paste snips 
with a textual look but a non-textual representation into the 
Definitions window. Lots of things are not present when one is running a 
teaching language; why is the absence of this particular feature 
considered "crippling", especially when they are not using it 
deliberately? --PR
