And so we touch upon Global Variables again. If you want the variable strComputer to be available outside of the function it has to be global. This is, generally, frowned upon by people on here (I'm a little more accepting of them). You can pass the VALUE of strComputer outside of the function by making the Function equal to StrComputer

As it stands the strComputer variable in that function is redundant. It doesn't do anything other than assign itself a value. You could just as easily do

Another way to return multiple values from a function is to return an array or a dictionary.

Dim dicRet

Set dicRet = SomeFunc()
WScript.Echo dicRet("Foo")
WScript.Echo dicRet("Other")

Function SomeFunc
Dim dicTemp

Set dicTemp = CreateObject("Scripting.Dictionary")
dicTemp.Add "Foo", "Bar"
dicTemp.Add "Other", "Things"

SomeFunc = dicTemp
End Function

I'd never thought to use a dictionary to return multiple items from a function. I've created a global dictionary for use, but never directly returned a dictionary. Thanks for the tip, that'll eliminate most of the global variables I have in my code.

Ooops..good catch ehvbs. That is what I get for just typing out code instead of testing it first.
