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)
Syntax terms
| %one | This function always returns 1. |
|---|---|
| scr_item | The screen item for which attributes are to be returned. This can be a variable of the form %screen:item or a screen item name variable of the form :%string. |
Example
This code fragment sets the modified attribute for screen item bar in screen foo:
%rc = $Screen_mod(%foo:bar)
