The
Exists
method is used to determine whether a key already exists in the specified
Dictionary
. Returns
True
if it does and

The following code uses the

Dictionary
object and, if it does, changes its corresponding item value.
Code:

dim guitars
set guitars=CreateObject("Scripting.Dictionary")
guitars.Add "e", "Epiphone"
guitars.Add "f", "Fender"
