<h4>Description</h4>
|
|
|
|
<pre>discontiguous(Functor/Arity)
|
|
discontiguous(Functor1/Arity1, Functor2/Arity2, ...)
|
|
discontiguous([Functor1/Arity1, Functor2/Arity2, ...])
|
|
|
|
discontiguous(Functor//Arity)
|
|
discontiguous(Functor1//Arity1, Functor2//Arity2, ...)
|
|
discontiguous([Functor1//Arity1, Functor2//Arity2, ...])</pre>
|
|
<p>
|
|
Declares discontiguous predicates and discontiguous grammar rule non-terminals. The use of this directive should be avoided as not all Prolog compilers support discontiguous predicates.
