Bart，你的剧本再次被打破:(
Bart, your script is broken again :(
是的。我现在肯定会选择`（hex 60）来保持它
仅限ASCII。

ASCII-only.

给我一个啰嗦404.
< http：// www .elsop.com / quick / quick.cgigives，检查常见问题解答URL，
在Microsoft Script Debugger Download：之后，3.2结束：

Gives me a long-winded 404.
<http://www.elsop.com/quick/quick.cgigives, checking FAQ URL,
Just after "Microsoft Script Debugger Download:", end of 3.2 :
00585 Error: 404 Not Found http://msdn.microsoft.com/downloads/list/web

提供虚假信息。说介于0和1之间。还说从当前时间播种
这可能是一般的，但不是一个语言要求。我建议参考标准，15.8.2.14，
或只是复制这三行。
Gives false information. Says "between 0 and 1". Also says "seeded
from the current time" which is probably generally true but is not a
language requirement. I suggest a reference to the standard, 15.8.2.14,
or just copying those three lines.

Could be taken as implying that the page is *only* about that. Fix is

顺便说一句，有权访问Vista的人是否会在IE中检查一个网页
？这只是报告某些计算文本所说的问题。

Astro的东西通过astron-1.htm，gravity0.htm; quotings.htm，pascal.htm等。
无编码。回复之前的行情。剪得好。写清楚。不要邮寄新闻。
By the way, would anyone with access to Vista care to check a Web page
in IE? It''s just a matter of reporting what certain computed text says.
