<h2 class="code">discontiguous/1</h2>
<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.
</p>
<h4>Template and modes</h4>
<pre>discontiguous(+predicate_indicator_term)
discontiguous(+non_terminal_indicator_term)</pre>
<h4>Examples</h4>
<pre>:- discontiguous(counter/1).
:- discontiguous(lives/2, works/2).
:- discontiguous([db/4, key/2, file/3]).</pre>
