在excel VBA中声明函数参数

Question

I have two functions (one of which is called inside the other) which share some variables as arguments, as the following example:

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

Is there a way to declare the recurring variables (a, b, and c) only once outside both of these functions, something like this:

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

or are those arguments specific to their parent functions?

Answer 1

a way to do it, define global variable and don't use them as parameters for your function.

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
