Thanks to Jesse and andy_mc for assistance.

function dist(x1#,y1#,x2#,y2#)
distance# = sqr((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1))
return distance
end function 

OR

d = sqr((x2-x1)^2+(y2-y1)^2)

This isn't actually the distance between two squares, but rather two points in a 2D space.

The distance between two squares should be computed (if they are not both axis-aligned) by finding which vertex is closer to the other square (so you'll end up with two most closer vertices, one for each square), and getting the distance between these close vertices.
