Thanks for your reply Stefan.

In this case, is it possible to recreate the capabilities of other types 
of response boxes (for example, formula response boxes) without too much 
effort?  For instance, in my original example, is there an easy way to 
use &cas() to see if the &cas-calculated characteristic polynomial is 
equivalent to the student's response, just as a formula response box 
could (and with as many optional ways of doing so) if we knew an answer 
beforehand?

Your examples online have been my inspiration so far, and I am grateful 
that you share your source code.

No, his name is Jeff.  I have thought about changing my last name however...

Thanks Again,
