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, one would want to set the screen item's modified attribute so that the legacy code would know it's 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)
