     You can do what Guy suggests.	
I like to also make the problem a radiobuttonresponse problem rather than
leave it as numericalresponse.
Then the prog will randomize the order for you. This is superficial, in the
sense that the same number is still the answer, but at least it is not
necessarily "C". 

Since you already have the answer (and wrong answers) calculated in the perl
script, just delete the numericalresponse block, insert a
radiobuttonresponse block and put the answer variables into the foils.

A little more tedious than just using a numericalresponse problem, but it is
not hard.	

What is harder, is making sure that none of your calculated wrong answers
ever coincide with each other or with the correct answer.

Note also, in a numericalresponse type exam question, that if your tolerance
parameter is not small, then it is possible for two or more apparently
different choices to be marked correct, because they fall within the

This kind of situation is avoided if you make it radiobuttonresponse.

The downside is that radiobuttonresponse foils always seem to get a linefeed
between them in the printout and your exam printout will require more paper.
