% Define variables:
%   ax     -- x-position of point a
%   ay     -- y-position of point a
%   bx     -- x-position of point b
%   by     -- y-position of point b
%   result -- Distance between the points

% Get input data.

ax = input('Enter x value of point a:   ');
ay = input('Enter y value of point a:   ');
bx = input('Enter x value of point b:   ');
by = input('Enter y value of point b:   ');

% Evaluate function
result = dist2 (ax, ay, bx, by);
 
% Write out result.
