Returns the name of the last nondeleted main object (entity) in the drawing

(entlast)
The entlast function is frequently used to obtain the name of a new entity that has just been added with the command function. To be selected, the entity need not be on the screen or on a thawed layer.

============

您的情况应先建立空的选集 (setq Ofst_ss (ssadd))
在回圈内加入 (entlast)

==>
(command "Chprop" Ofst_ss "" "La" (Getvar 'Clayer) "")
