declare function Setmouse ( byval x as long = -1, byval y as long = -1, byval visibility as long = -1, byval clip as long = -1 ) as long

result = Setmouse([ x ] [, [ y ] [, [ visibility ] [, [ clip ]]]])

(For each parameter, -1 is a special value indicating "no changes.")
optional - set x coordinate
optional - set y coordinate
optional - set visibility: 1 indicates visible, 0 indicates hidden
optional - set clipping: 1 indicates mouse is clipped to graphics window, 0 indicates no clipping

Return Value:
Zero (0) on success, non-zero to indicate failure.

Setmouse will set the (x, y) coordinates of the mouse pointer, as well as setting its visibility. The mouse position is set using the x and y parameters. The mouse will be visible if visibility is set to 1, and invisible if visibility is set to 0. Setmouse is intended for graphics modes initiated using the Screen (Graphics) statement only.

The error code returned by Setmouse can be checked using Err in the next line. The function version of Setmouse returns directly the error code as a 32 bit Long.
