Hi, 
 
   I am looking for solutions for any three star problem in EOPL
textbook(Essentials of programming languages). The solutions have to
be for 'three star' problems from chapters 5, 6 or 7 of the EOPL
textbook(2nd edition). Each 3 star solution is worth $50 and has to be
complete with scheme code and explanations. It's urgent!!
 
Thanks, Tim 

I'm not sure if this is what you're seeking, but there are code
schemes for that textbook on this web site of the CS department at
University of Indiana:
http://www.cs.indiana.edu/eopl/code/interps/

This link seems to provide you with a list of nearnly all the problems
featiured in the EOPL Book along with the solution and code for each.
It also features downloadable slides to accompany the lectures from
the book for the University of Utah. While the dates are not as
relavent, I believe that the actual data and pure coding should help
you. The link is as follows...

Here is also another link similar to the one at the University of
Indiana but this features a few more iteams and sub-folders with the
relavant data...

However if in the future you are seeking general information on the
book, I feel that this link will provide usefull to you as it sums up
the book nicley...

Anyway, I wish you all the best of luck in finding the solutions for
the programming assesments and hope that these links are of some use
to you.
