在excel VBA中声明函数参数

Question

我有两个函数（其中一个在另一个内部调用），它们将一些变量作为参数共享，如下例所示：

Public Function f1(a as Double, b as Double, c as Double)
"code"
End

Public Function f2(a as Double, b as Double, c as Double, t as Integer)
var = f1(a, b, c)
"code"
End

有没有办法在这两个函数之外只声明一次重复变量（a，b和c），如下所示：

Dim a As Double, b As Double, c As Double

Public Function f1(a, b, c)
"code"
End

Public Function f2(a, b, c, t as Integer)
var = f1(a, b, c)
"code"
End

或者那些特定于其父函数的参数？

Answer 1

一种方法，定义全局变量，不要将它们用作函数的参数。

Dim a As Double, b As Double, c As Double

Public Function f1()
"code use a,b and c"
End

Public Function f2(t as Integer)
var = f1()
"code use a,b and c"
End
