Run-time data and visual layout definition data can be stored in a storage medium. The run-time data and the visual layout definition data can be associated with a terminal application, which is configured to communicate with a host server in blocks of data in accordance with a standardized synchronous terminal protocol. A visual screen for the terminal application can be generated by combining the layout data and the run-time data. The generating can occur when the terminal application is disconnected from the host server or host server emulator. The generated visual screen, which is a screen of a front-end of a terminal application interface, can be presented.
