Use this record-level keyword to specify that the record format you are defining will be displayed using a window. A window is information that overlays part of the display. A window is usually smaller than the actual workstation display, and can be positioned anywhere on the display. The *NOMSGLIN and *RSTCSR parameters for this keyword are not supported. The *NOMSGLIN parameter specifies that the message line within the window should be removed and placed at the bottom of the display. The *RSTCSR parameter specifies that the user should be allowed limited function when the cursor is outside of the window.
