瞭解VBScript中的Const表達式

Question

好吧，我試圖理解Const表達式中的限制VBScript。除了文字之外，我無法使用任何東西。什麼the docs say是：

Literal or other constant, or any combination that includes all arithmetic or logical operators exceptIs.

所以，如果「包括所有的算術或邏輯運算符」，那麼在邏輯上我希望我可以做這樣的事情：

Const X = (1 + 2) 

但是，這帶來的錯誤「預期字面常量」。我發現一個有趣的答案here，允許一個作弊，在一定程度上，讓上面的功能也可以用：

Execute "Const X = " & (1 + 2) 

但我的問題是關於標準定聲明。如果偶然的文件說像「表達可能只是字面意思」，那麼我永遠不會問。
那麼還有什麼我可以使用（除了文字）？

Answer 1

Script56.chm說，在備註部分執行以下操作：

Constants are public by default. Within procedures, constants are always private; their visibility can't be changed. Within a script, the default visibility of a script-level constant can be changed using the Private keyword.

To combine several constant declarations on the same line, separate each constant assignment with a comma. When constant declarations are combined in this way, the Public or Private keyword, if used, applies to all of them.

You can't use variables, user-defined functions, or intrinsic VBScript functions (such as Chr) in constant declarations. By definition, they can't be constants. You also can't create a constant from any expression that involves an operator, that is, only simple constants are allowed. Constants declared in a Sub or Function procedure are local to that procedure. A constant declared outside a procedure is defined throughout the script in which it is declared. You can use constants anywhere you can use an expression.

斜體位以上使的無義「包括所有的算術或除了邏輯運算符或任何組合爲」權利要求。
