Using an extracted string in a String descriptor

If you use an Extract action to read text from the screen into a string variable (see Extract action (<extract> element)) then in a subsequent screen you can use the string variable in the String input field of a String descriptor.

For example, in ScreenA you might read a company name from the session window into a string variable named $strTmp$, using an Extract action. Then in ScreenB you could use $strTmp$ as the string to be searched for in a String descriptor.

You can do this when extracting multiple lines of text if you have the Wrap option set to true.
