Extract action (<extract> element)
The Extract action captures text from the session window and stores the text into a variable. This action is very useful and is the primary method that the Macro object provides for reading application data (short of using programming APIs from the toolkit).
If you have the HCL ZIE Host Access Toolkit product, then you can use the Extract action to read data from any of the available data planes. For more information see Using the Toolkit to capture data from any data plane.
