Global definirá uma lista de uma ou mais (separadas por vírgula) variáveis que podem ser acedidas e modificadas dentro <a href="pt_subroutine.html" class="wikilink1" title="pt:subroutine">Subroutine</a>s e <a href="pt_function.html" class="wikilink1" title="pt:function">Function</a>s. Estas variaveis globais podem ser também arrays.
</p>
<p>
Variaveis globais têm que ser definidas fora de qualquer bloco e antes de chamar a <a href="pt_function.html" class="wikilink1" title="pt:function">Function</a> ou <a href="pt_subroutine.html" class="wikilink1" title="pt:subroutine">Subroutine</a>.
