; Open the states Shapefile in the examples directory. 
myshape=OBJ_NEW('IDLffShape', FILEPATH('states.shp', $ 
   SUBDIR=['examples', 'data'])) 
 
; Get the number of entities so we can parse through them. 
myshape->GetProperty, N_ENTITIES=num_ent 
 
; Read all the entities.  
FOR x=1, (num_ent-1) DO BEGIN 
   ;Read the entity x 
   ent = myshape->GetEntity(x) 
   ;Clean-up of pointers 
   myshape->DestroyEntity, ent 
ENDFOR 
 
; Close the Shapefile.
