{{DISPLAYTITLE:_SCREENMOVE}}
|
|
The [[_SCREENMOVE]] statement positions the program window on the desktop using designated coordinates.
|
|
|
|
|
|
{{PageSyntax}}
|
|
: [[_SCREENMOVE]] {{{Parameter|column&}}, {{Parameter|row&}}|_MIDDLE}
|
|
|
|
|
|
{{Parameters}}
|
|
* Positions the program window on the desktop using the {{Parameter|column&}} and {{Parameter|row&}} pixel coordinates for the upper left corner.
|
|
* '''_MIDDLE''' can be used instead to automatically center the program window on the desktop, in any screen resolution.
|
|
|
|
|
|
{{PageDescription}}
|
|
* The program's [[SCREEN]] dimensions may influence the desktop position that can be used to keep the entire window on the screen.
|
|
* Use [[_DESKTOPWIDTH]] and [[_DESKTOPHEIGHT]] to find the current desktop resolution to place the program's window.
|
|
* On dual monitors a negative {{Parameter|column&}} position or a value greater than the main screen width can be used to position a window in another monitor.
|
|
* '''A small delay may be necessary when a program first starts up to properly orient the screen on the desktop properly.''' See [[_SCREENEXISTS]].
|
