Re: [WWdevel] Sequential problems and hardcopy

[P. G. L. <gl...@um...>]

Hi Davide,

Re: Hardcopy generation and access to answers, this summer I put a hack 
into Hardcopy.pm to make it grab student answers for versioned (gateway) 
sets so that I can output those on a graded set.  Without having extensive 
testing to determine the net impact of this on the penalty thereby 
incurred, it seems that this at least works.  I suspect that this is not 
an answer to your question, but hopefully it's at least a step away from a 
non sequitor.

I'll add that I didn't bother to try and insert the student's answer in 
the answer blanks, instead simply listing it in the same manner the 
Correct Answer is included.
