{{DISPLAYTITLE:_MOUSEMOVEMENTY}}
The [[_MOUSEMOVEMENTY]] function returns the relative vertical position of the mouse cursor as positive or negative values. 


{{PageSyntax}} 
: {{Parameter|verticalMove}} = [[_MOUSEMOVEMENTY]]


* Returns the relative vertical cursor pixel position compared to the previous cursor position. Negative values are up moves.
* '''Note:''' A [[_MOUSESHOW]] statement will disable [[_MOUSEMOVEMENTX]] or [[_MOUSEMOVEMENTY]] relative mouse movement reads.
* Can also be used to check for any mouse movements to enable a program or close [[Screen Saver Programs]].
* Sets the mouse to a relative movement mode which can be read by [[_WHEEL]] instead of [[_AXIS]] as mouse [[_DEVICES|device]] 2.


''Example:'' MOD is used to keep vertical movement of circle and cursor inside of the SCREEN 13 window(200).
