The Fox is right of course... The Fox is always right (lol).
Since the American style of reading is from Left to Right and VFP is an American language program I would say Upward Diagonal is from Lower Left to Upper Right. Otherwise we'd be reading backwards.

>>From a math article I was able to find, "the slope computed as m = (y2 - y1) / (x2 - x1)." If you set the left-most part of the line at (0, 0) then a lower left to upper right line has a positive slope due to the fact that both the x and y values are increasing, where an upper right to lower left line has a negative slope (y goes from 0 to -something, while x increases). I'd say that a line with a positive slope goes "upward" and a line with a negative slope goes downward.
