我修改了rebodex应用程序，以便可以通过键入rebodex随时从rebol的控制台调用它。要显示应用程序的标题，我需要将其存储在
中app-title: system/script/header/title
因此可以在以后使用
view/new/title dex reform [self/app-title version]
虽然有效但你可以看到我已经将var命名为“app-title”，但如果我使用“title”，那么窗口标题会显示奇怪的东西（vid代码）。为什么？

答案 0 :(得分：1)
你有这个
title：fld return
所以title是rebol对象......不是文本。
