Unwrap Text option
This option was originally intended to be used with the HCL ZIE Host Access Toolkit product and only when the Continuous Extract option was set to false. However, you can also use it without the toolkit, and you can use it with the Continuous Extract option set either to false or true.
When you set Unwrap Text to true, the macro runtime uses not only the row and column pairs in the Extract window but also the field boundaries in the session window in determining the data to collect. The macro runtime returns an array of strings (if you are using the toolkit) or a single string of concatenated strings (if you are not using the the toolkit).
Do not confuse the Unwrap Text option with the Wrap option of the String descriptor, which is based on a rectangular block of text rather than fields (see How the macro runtime searches the rectangular area (Wrap option)).
