Full-Screen CMS and the CMSOUT Window
While you are in the XEDIT environment, the CMSOUT window may be displayed at various times. If full-screen CMS is on before XEDIT writes to the screen, the CMSOUT window may be displayed followed by the XEDIT window or the particular window that has been set up to display the file.
When you return to the XEDIT environment from CMS subset mode, the CMSOUT window is shown, followed by the window set up to display the file.
If you are already in XEDIT and you set full-screen CMS ON, the CMSOUT window is shown if the CMSOUT window has never been shown in this XEDIT session and you issue a CMS command, or if an XEDIT message is issued that cannot fit into the XEDIT message area.
