Re: [eclipse-clp-users] Error_Handler

Dear Marco,

  My program does not execute a call(X). So I am not sure why the error. Following is the program that resembles my intentions of the program.

solveError(X):-
Y #:: 1..3,
X #:: 1..10,
goal(X),
member(Y,[1]),
search([X],0,most_constrained,indomain,complete,[]).

goal(X):- (member(X,[1,2,3]);true).


The intention is simple. If all the possible solutions of X via the member function in goal(X) are exhausted, look for more solution through search. Though the program shown over here works fine, my original source code has some issue and it aborts abnormally. Your email surely provided me a direction to find my solution. Hopefully I will fix it.

Thanks for the help.

Cheers,
Shrirang

Dear Shrirang,

I notice only now that the error you get gives more precise information:
it also says what is the predicate that raises the error: call(_1933).

This means that your program executes call(X), where X is a variable.
You cannot invoke a predicate which is a variable.

Hope this helps.

Marco
