Modify scripts with another script

[HippyCraig]

I am working on a script to modify a batch of scripts in a folder, I have a script action as follows:

'Create Sub Call
Option Explicit

Dim objApp, objStep, objMacro

' create VisBuildPro app object
Set objApp = CreateObject("VisBuildSvr7.Application")
objApp.Project.Load "%PROCFILES_FULLPATH%"

Set objStep = objApp.Project.Steps(vbldStepMain).Add("Subroutine Call", 6)
objStep.Name = "Get Version History List"
objStep.Indent = 2
objStep.Property("SubName") = "SUB Get Version History List"
objStep.Property("Expand") = -1

objApp.Project.Save


When I run the script it modify's creates the following in a script file:

<step action='Subroutine Call'>
<Expand type='2'>-1</Expand>
<SubName>SUB Get Version History List</SubName>
<indent type='3'>2</indent>
<name>Get Version History List</name>
</step>


If I create the same step manually it looks like this:

<step action='Subroutine Call'>
<Expand type='11'>-1</Expand>
<SubName>SUB Get Version History List</SubName>
<indent type='3'>2</indent>
<name>Get Version History List</name>
</step>


The main difference between the two is teh type value of the Expand in one its 11 and when I create it through script its a value of 2

My question is what does the value of type represent and how do I change it? Also what is the type value in indent property represent?
