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).
tent_set(String, 1).

   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
