Passing Discovery Pattern variables to a pattern step using Javascript

[Bob Mullineaux]

Is there a way to pass a Discovery Pattern variable to a Step using javascript?  e.g. passing information obtained in a prior step such as the $WIN32_ComputerSystem.UserName to the javascript in the next step?

Yes, you can access the individual variables in the result of a WMI query in a Javascript step such as an EVAL() block.

In an EVAL() block you'd access it using ${Win32_ComputerSystem.UserName}

hi @Bob Mullineaux , 

Here are the few example of how EVAL scripts work in the patterns. Please take a look the below kb article.
