I think it's impossible. You can use filters for your selection.

Why not create a new selection set out of the first adding only 150 items from the first??

Not sure what you're trying to do.
If you have a selectionset ss,
(setq count (sslength ss))
(if (> count 150)
  (repeat (- count 150)
    (ssdel (ssname ss 0) ss)
  )
)

You may want to retain the first 150 items like this.

Code: [Select]

(defun c:test ()
  (setq ss (ssget))
  (setq i (sslength ss))
  (while (and (setq ename (ssname ss (setq i (1- i))))
              (> (sslength ss) 150)
         )
    (ssdel ename ss)
  )
 (sslength ss)
)
