How much maximum number of selection sets

In "Error code " catalog (Appendix C--AutoLISP Error Codes) I've got table
value 3 ,this meaning is exceeded maximum number of selection sets,my
question is ,how much maximum number of selection sets?

 

Hi Jeff,thanks.

 

Hi Jeff,is it my script true or wrong?
(setq ss (ssget "x" '((0 . "LINE"))))
(if ss
(= (getvar "errno") 3)
(alert "\nYOUR CHOOSE,OVER THE MAXIMUM NUMBER OF SELECTION SETS"))

 

Not Jeff.... but....

If you are testing code do something like this:

Code:

(setq ss nil) ;; this will avoid the error message you are getting

(if (setq ss (ssget "x" '((0 . "LINE"))))
(progn

;; do whatever here...

))

 

Hi Luis,I want error work and how error work,not avoid from error message

 

Hi Ade,
Try this little routine that will exceed the number of SelSets and report
the error to you. Then use the second one to clear them out. This should
give you the answers you are looking for.

(defun c:sstest (/ count *error*)
(defun *error* (msg)
(princ (strcat "\nError message: " msg))
(princ (strcat "\nError number: " (itoa (getvar "errno"))))
)
(setq count 0)
(repeat 150
(setq count (1+ count))
(set (read (strcat "ss" (itoa count))) (ssget "x"))
)
)

(defun c:ssclear ()
(vl-load-com)
(foreach x (atoms-family 1)
(if (= (type (eval (read x))) 'PICKSET)
(set (read x) nil)
)
)
(vlax-for x (vla-get-selectionsets
(vla-get-activedocument
(vlax-get-acad-object)))
(vla-delete x)
)
(gc)
(princ)
)

Hi Jeff, yes that is I'm looking for,thanks very much for your spend time to
answer my question

 

One thing to keep in mind here, the user DID NOT exceed the maximum number
of selection sets. The custom programming exceeding the maximum number of
selection sets. The user can run Autocad all day long and will never run out
of selection sets, UNLESS he ran some custom programming that did not free
them when it was done. When you create a selection set, you should nil it
out when you are done with it, also nil it out before you use it, just in
case it wasnt set to nil by the last program that used it.

 

yep, just love those programmers who think global vars are the way to go.
One more reason to keep things local.
