View Full Version : Passing a parameter by reference

08-09-2004, 07:42 PM
It's been a while since I worked with ASP, I've forgotten some concepts. I know vb (and hence vbscript) passes arguments by reference. The following page gave me 100, I expected 1000:

Dim a

a = 10

call test1(a)

Response.Write a

Sub test1(b)
b = 100
End Sub

Sub test2(c)
c = 1000
End Sub

Why's that test2(b) did not change the value of b in test1? Is it because parameter variables are not passed by reference?

I think VB and VBScript actually pass by value...I may be wrong though.

However, just to be sure, try adding "ByRef" in front of the appropriate paraemter in your parameter lists.
