{{DISPLAYTITLE:_DEST}}
The [[_DEST]] statement sets the current write image or page. All graphic and print changes will be done to this image.


{{PageSyntax}}
:[[_DEST]] {{Parameter|imageHandle&}}


{{PageDescription}}
* {{Parameter|imageHandle&}} is the handle of the image that will act as the current write page.
* '''_DEST 0''' refers to the present program [[SCREEN]]. You can use 0 to refer to the present program [[SCREEN]].
* [[_DEST]] [[_CONSOLE]] can set the destination to send information to a console window using [[PRINT]] or [[INPUT]].
* If {{Parameter|imageHandle&}} is an invalid handle, an [[ERROR Codes|invalid handle]] error occurs. Always check for valid handle values first ({{Parameter|imageHandle&}} < -1).
*''Note:'' Use [[_SOURCE]] when you need to read a page or image with [[POINT]], [[GET (graphics statement)|GET]] or the [[SCREEN (function)|SCREEN]] function.
