The '''_SCREENMOVE''' statement positions the program window on the desktop using designated coordinates or the _MIDDLE function.

{{PageSyntax}}
|
|
:: '''_SCREENMOVE''' {'''''column&'', ''row&'''''|_MIDDLE}
|
|
|
|
|
|
{{Parameters}}
|
|
* Positions the program window on the desktop using the ''column'' and ''row'' pixel coordinates for the upper left corner.
|
|
* '''_MIDDLE''' can be used instead to automatically center the program window's position on the desktop in any screen resolution.
|
|
|
|
|
|
''Usage:''
|
|
* The program's [[SCREEN]] dimensions may influence the desktop position that can be used to keep the entire window on the screen.
|
|
* Use [[_SCREENIMAGE]] handle with [[_WIDTH (function)|_WIDTH]] and [[_HEIGHT]] to find the current Windows desktop resolution to place the program's window.
|
|
* On dual monitors a negative ''column'' position or a value greater than the main screen width can be used to position a window left or right.
