Press the number button either choosing objects with mouse.

I want to get the amount of objects.

(setq amount (sslength (ssget)))

or

(setq amount (getint "\nAmount of details: "))

to choose from at the same time.
Does it possible?

Not as a single prompt (at least not without recreating your own version of ssget using a grread loop).

 

I would instead suggest something like this:

(defun c:test ( / qty tmp )
    (initget 6)
    (if
        (setq qty
            (cond
                (   (getint "\nNumber of details <select>: "))
                (   (setq tmp (ssget))
                    (sslength tmp)
                )
            )
        )
        (progn
            (princ (strcat "\nThe user specified " (itoa qty) " object" (if (= 1 qty) "." "s.")))
            ;; do something else
        )
    )
    (princ)
)

Lee Mac  It's a variant too, just extra press.  Thank you.
