MWAPI - MODAL

Draft MDC Standard

A window for which the MODAL wattribute is defined is referred to as a modal window.

When a modal window is visible, other windows may be disabled. A MODAL wattribute value equal to "PARENT" indicates that the modal window disables only its parent window. A MODAL wattribute value equal to "ANCESTORS" indicates that the modal window disables all of its ancestor windows. A MODAL wattribute value equal to "APPLICATION" indicates that the modal window disables all active windows defined in ^$WINDOW except itself.

If an application attempts to create a child window of a modal window which is not also a modal window, an error condition occurs with an ecode = "M54" and $EREF containing a value that indicates the ssvn reference for which the error occurred.

If the window is in build mode the wattribute may be set and referenced but is ignored.
