Leapwork’s Green Screen building blocks are purpose built blocks for automating text based terminal applications (green screen or mainframe style UIs) through a supported terminal emulator.
They let you connect to an active terminal session, then read and write screen content using cursor position, keys, and table interactions, so you can validate messages, extract values, and navigate workflows even when there are no modern UI controls.
A key benefit is Leapwork’s field recognition for green screens, which detects the relationship between protected labels and the unprotected input field that follows, making it faster and more reliable to get or set values in terminal forms.
