Invoke Full-screen Panels

Once defined and saved, a panel can be displayed immediately. Panels for display are usually selected using an NCL procedure containing an &PANEL statement. Other NCL statements such as &LOGON can nominate a panel for display under specific circumstances.

If you try to display a panel that has not been defined, the procedure terminates and displays an error message. You can use the &CONTROL PANELRC statement to receive notification of processing anomalies (including referencing non-existent panels). Your procedure can detect this fact and pre-empt termination to continue processing.
