Depending on the TN3270 debugging settings you have set and on the last state of the mainframe display, the display either
launches automatically when debugging starts, or you need to launch it manually.
The IDE preserves the last state, size, and position of the embedded Rumba Mainframe Display:
- If the embedded Rumba Mainframe Display is open when debugging ends, it opens automatically next time you start debugging.
- If you close the embedded Rumba Mainframe Display, the session is still connected until debugging ends.
