It is difficult to provide any speicifc help to you, as you have not 
really given enough of your program. Most importantly, you have not 
given your code for check/4, the goal that you say is causing ECLiPSe to 

Also, what precisely do you mean by ECLiPSe "always gave me abort" -- do 
you mean ECLiPSe raise an error? If so, there should have been an error 
message printed, which will give you some idea of what went wrong, and 
you should include this in your report.

If on the other hand, the ECLiPSe process aborted (i.e. crashed), then 
you should state this clearly, and give any messages that you got when 
this happened.
