Set modified attribute in screen item
This function sets the modified attribute for a screen item. While it might be useful in some normal full-screen applications, it is probably most useful in applications that receive output from a non-full-screen source but populate a screen from that source, in order to be able to use legacy full-screen code.
When setting a screen item from the external source, set the screen item's modified attribute so that the legacy code can tell that the item has changed.
Under Model 204 7.8 and later, $Screen_mod is callable.
Syntax
[%one =] $Screen_mod(scr_item)
