how to retain previous selection

[blasto]

hi there,
I need to create a selection set [plsset] as follows:
and when I do so, "plsset" selection also becomes previous selection set for autocad. any idea on how to avoid that and retain the "real_previous" selection as previous selection? or reset the previous selection completely? thanks


(defun c:sel()
(setq real_previous (ssget "P"))
(setq plsset (ssget "X" '((0 . "LWPOLYLINE"))))
)

Like this...


(defun c:sel()
(setq real_previous (ssget "P"))
(setq plsset (ssget "X" '((0 . "LWPOLYLINE"))))
(command "._select" real_previous "")
)

thanks for the suggestion. I've tried using (command "._select") as you said but I need to do that selection inside a "command reactor" call back subroutine thus I saw that it can not be used. If it was possible with vl functions it would be wonderful because they do not use the command interface.

(sssetfirst nil real_previous)

Should do the trick.
