如果在 Rebol 的控制台中进行测试，则会给出

为什么它会返回以及如何防止这种情况（如果可能）？

首先：REBOL 脚本以
REBOL [...]标头开始，因此 REBOL 解释器将忽略此标头之前的所有内容。其次：标签是 REBOL 中的有效数据类型。因此，在执行示例脚本时，ask ...表达式后面还有三个值，最后一个值 () 将返回为你的脚本的结果。为了防止这种情况，您可以在希望脚本结束的位置添加一个
quit，即在示例中的ask表达式之后。First: a REBOL script starts with the
REBOL [...]header, so everything up to this header will be ignored by the REBOL interpreter. Second: tags are a valid datatype in REBOL. So upon executing your example script, there are three more values following theask ...expression and the last of those values (</body>) will be returned as the result of your script.To prevent this, you can add a
quitwhere you want your script to end, i.e. after theaskexpression in your example.<标题>不是有效的 HTML 标记。你的意思是
<header> is not a valid HTML tag. You mean <head>
