Function for distance of objects

I've used an old formula and put it into a function to save the user of my snippet time.
After inserting this into your program you can test distances between object by using the command distance(object 1,object 2)

                                    function distance(obja.objb)
xa#=object position x(objba)
ya#=object position y(obja)
za#=bject position z(obja)

xb#=object position x(objb)
yb#=object position y(objb)
zb#=bject position z(objb)

distance#=sqrt((xa#-xb#)^2 + (ya#-yb#)^2 + (za#-zb#)^2)
endfunction distance#
