Trata-se de uma instrução com várias formas. IF avalia <em>booleanexpr</em>, que se for verdadeira executa <em><a class="explain" href="en_programsyntax.html">statement(s)</a></em> após THEN. Para executar vérias linhas de código ter-se-á que pôr ENDIF no fim. Para executar código quando <em>booleanexpr</em> é falsa então é usado ELSE.
