MWAPI - MODAL

1995 Version of ANSI (Equivalent to Current ISO Version) of 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 $ECODE containing ",M?9," and $EREF containing a value that indicates the ssvn reference for which the error occurred.
