Using Command SELECT with ssget

Hello everyone.

I am having a mental blank as i am sure i know the solution to this but cannot remember

I am trying to have a shortcut to select all xrefs starting with X*

I have tried this but i does not work.

(defun c:xrss ()
(command "SELECT"
(ssget "X" (list
(cons 0 "INSERT")
(cons 2 "X*")
			)
)
""
)
)

However this does work

(defun c:xrerase ()
(command "erase"
(ssget "X" (list
(cons 0 "INSERT")
(cons 2 "X*")
			)
)
""
)
)

Can anyone explain what is happening here. I don't need a quick fix but would like to understand the process

The

(ssget "X" (list(cons 0 "INSERT")(cons 2 "X*"))

part creates the selection set, what are you trying to do with "SELECT"?

Try

(sssetfirst nil(ssget "X" (list(cons 0 "INSERT")(cons 2 "X*")))

Thank tombu

I was unaware of the function.

To make sure I understand correctly "sssetfirst" used to instruct autocad to grip something?

(sssetfirst gripset [pickset])

gripset is redundant and is always nil

pickset is a selection set you want to grip (select to autocad user)

In r14 (not 2014) early days of grips objects gripped were a gripset and objects selected were a pickset. After that they simplified it the way it is now. So as little as possible code would have to be rewritten we now use nil instead of gripset.

Thanks for the history. 2011 was my first version so i am missing a lot of the history.

I started with r12 with SoftDesk plugins. Showing my age, but I've see posts by others who started earlier.
