This article describes the difference between using the GetObject and CreateObject commands in Surfer Scripter.

When you begin a script to call Surfer, the GetObject function uses an existing open instance of Surfer and the CreateObject function opens a new Surfer application window.

For example, if you want the script to open Surfer and perform actions, use CreateObject:

    Dim SurferApp As Object
    Set SurferApp = CreateObject("Surfer.Application")
    SurferApp.Visible = True

If you want to open Surfer first, and then run the script and have the script use that instance of Surfer that is already open, use GetObject:

    Dim SurferApp As Object
    Set SurferApp = GetObject(, "Surfer.Application")
    SurferApp.Visible = True

This is useful if you have multiple versions of Surfer installed on the computer and you want to run a script using a particular version, or if you want to perform some actions in Surfer first and then run the script and have the script apply the actions to the open file.
