if i have an array z[] of points(x,y)

how do I get the x and y variables?

i.e.

z[0]'s x and y value

or actually, is there a function for determining distances between two TPoint (obv i could just do this myself if i could get the x and y values)? (though i'd still like to know the answer to my original question)

z[0].x
z[0].y

distance(x1,y1,x2,y2);

i kind of thought so but wasn't sure, thanks
