Mark I'm having fun with this code. Just one question; why add 31
pixels as opposed to another number of pixels?

Hi Ray,
Now I'm thinking, why did I write a function for the screenLoc only?
So, here's a general solution.
// usage: pointColor("100,200") or
// pointColor(100,200) or e.g.
// pointColor(the screenLoc)
function pointColor thePoint
if the paramCount is 2 then
put param(1),param(2) into thePoint
end if
put thePoint into myLoc
add 31 to item 1 of myLoc
add 31 to item 2 of myLoc
put thePoint,myLoc into myRect
export snapshot from rectangle myRect to myPixels as PNG
set the text of the templateImage to myPixels
put char 1 to 4 of the imageData of the templateImage into myPixel
reset the templateImage
return charToNum(char 2 of myPixel), \
charToNum(char 3 of myPixel),charToNum(char 4 of myPixel)
end pointColor

Mark - I believe this is everything I need. Thanks! I especially like
you usage of the templateImage which keeps everything easy to work with
and no cleanup needed.
