Alright, here's the simple way to know generally.

I hope you know from math that x is _ horizontal and y is | vertical. 0x0y is at the bottom left hand corner of the screen. Maximumx and maximumy is top right corner of the screen. We see this when using: maxx and maxy. Try it,

code:

put maxx put maxy

So to find the center of the screen we would divide maxx / 2 and maxy / 2.

Use this program to figure out the coordinates on the screen using the mouse:

code:

var x, y, button : int %vars for the mouse where code loop %needs to be in a loop to keep on reading mouse data     Mouse.Where (x, y, button)    %code to find data on mouse     put " ", x, " ", y     %put mouse location     %check to see if button is hit     if button = 1 then         locatexy (maxx div 2, maxy div 2)         put "you clicked the button"         delay (1000)         cls     end if     cls end loop
