| ### Function PositionProperty ( func pred ) -> func pos ### Optional Arguments
Fail | any |  | Determines what to return in case of failure.
### Description Construct a functional `pos(<list> l) -> elt-ord^rat' which returns the position of the first element of `l' which suffices the predicate function `pred'. Return FAILURE if no such element exists in `l'. Note: Apparently `pred' must have `-> elt-alg^boo' out-signature. ### Examples l:=[Random(1000)..1000+Random(1000)];; f:=PositionProperty(i->i mod 17=0);; l; f(l);
