[eclipse-clp-users] Floundering case

Dear CLP users,



  I am working on to handle floundering case. Following is the script. Even if set the trigger on in my main script the suspension data does not change before and after the trigger is pulled.



   %Left function
   left(STR, Index, STRN):-
   (var(STR) -> suspend(left(STR, Index, STRN), 0, STR->inst)
   ; var(STRN),var(Index) -> suspend(left(STR, Index, STRN), 0, trigger(hello), S),
  get_suspension_data(S, priority, P),
        get_suspension_data(S, goal, G),
        get_suspension_data(S, module, M),
        get_suspension_data(S, qualified_goal, QG),
        get_suspension_data(S, invoc, I),
        get_suspension_data(S, state, Z), writeln([P, G, M, QG, I, Z])
   ; writeln("hello111"), substring(STR, 0, Index, _, STRN)).



I am not able to understand why ?



Thanks and Regards,

Shrirang Edgaonkar
