Setting Properties

[marcjs]

In BDD Rule processing, I understand how to set or define Properties using CustomSettings.ini and ZTIGather.xml, as well as directly in scripts, such as;

"oEnvironment.Item("ComputerName")=PC12345"

Question is how do you un-define a Property that's been set? Much like you would clear a variable that's been defined, is what I'm after ...

I've created some custom Wizards and have a situation where I need to dynamically define and un-define some Properties that are being used. Thanks for your help
