above code is displaying the association list of a multyline.  I need to find out the start and end coordinates of the mline .I can get the first point (association no 10) But how can get the 

Other end; there are association no 11 two times. I need the get value of second association no 11

Per the documentation, there is a DXF group 11 entry for every vertex of the MLINE, as such, you can use a 'massoc' function to retrieve the coordinates of all vertices, e.g.:

(massoc 11 <dxf data>)
