Retrieving a persistent variable like storing it very straight forward, just like common VBScript variables.
The only difference is, that the value you read from the variable will be taken from the database in that moment.
Dim MyVariable Set MyVariable = new PersistentVariable MyVariable.Name = "Welcome" MyVariable.Default = "Beep.wav" PlaySound MyVariable.Value
Before you read the content from the persistent variable you should define a Default value. This value will be returned in case nothing has been stored previously into the persistent variable.
Reading content from a persistent variable is the same as you would use a common variable, just that you have to read the Value property.
The above code passes the content of the persistent variable as parameter into the PlaySound function.
You can also access the variable directly in nearly any of the GSE blocks:
(Please note: in this screenshot the name of VBScript variable is "Welcome", while in the above code snippet it is "MyVariable". This is just because it was renamed after taking the screenshot. It has no functionaly reason.)
With nothing else configured the above persistent variable will be visible/accessible for the current script user only (the User scope is the default scope). To configure another scope (Global or Namespace) you have to change the Scope property.
You will find the 3.5 - Simple Script - Retrieve Variable in the download package which includes the above code (except line 6).
