Dear clp users,



 I wish to suspend a predicate till a change in tentative value occurs to one of its variables. I get the following error "out of range in suspend(cast(_612, _613), 1, _613 -> tent_chg, 'SUSP-5-susp') in module eclipse"



for the following script



:- lib(tentative).
solve(R):-
cast(Number,String),
tent_set(String, 1).


cast(Number,String):-
  (var(String)->
  suspend(cast(Number,String),
   1, String->tent_chg, Susp2);writeln(instantiated),true).



Whenever tentative value of String changes it should invoke cast(Number,String) is the intention.



Kindly guide me into this. I also checked the register_fornotification but its usage was not clear to me from the example.



Thanks and Regards,

Shrirang Edgaonkar
