Hello @Anonymous,
Thanks for posting. What application are you using?
It seems you need to reconcile layers, take a look at To Reconcile New Layers in the Drawing or How to turn off the unreconciled layers notification in AutoCAD.

If there are no unreconciled Layer(s), after you give it the rEconcile option, the prompt goes back to the standard Layer sub-prompt. But if there are, the prompt is different, and you can make use of that difference. Try this [minimally tested]:
(defun C:RecAllLay () ; <-- call it something different if you prefer
(command "_.layer" "_rEconcile"); [leaves you in the command]
(if (wcmatch (getvar 'lastprompt) "*list*"); is it the prompt for when there are some?
(command "*" ""); then [feed in the * and "" to end the Layer command]
(command ""); else [feed in only the closing ""]
); if
(princ)
); defun
You could choose something else if you prefer to check for, in place of "*list*" above -- anything that occurs in the prompt for Layers to rEconcile when there are any, but not in the basic Layer sub-prompt that comes back when there are not.
EDIT: Now I'm all confused.... I originally had "*name*" in place of "*list*" above, and it worked when I tested that. But then I noticed what I had missed, that the Rename option in the basic Layer sub-prompt includes that. So I changed it to "*list*" because that's not in the basic sub-prompt, and tried again, and now it doesn't seem to work. Somehow this approach should work, but it seems I've missed something. EDIT more: Now I think I had done something wrong in making some new un-Reconciled Layers, and when I did that right, it did work. But I'm still confused about its having worked right with *name* in there before, when even in the basic sub-prompt it should have seen that content and tried to give it the * before closing, but it didn't....

I just wrote that yesterday. The idea had occurred to me some time ago, but I hadn't done anything with it until the question was revived.

So now it's not working again for me, which makes me wonder what I did differently when it seemed like it did work. It works when there are no unreconciled Layers, but when there are, it doesn't feed in the * to reconcile them all, but only the "" Enter. So I put in a what's-the-last-prompt-really variable:
(defun C:RAL () ; = Reconcile All Layers
(command "_.layer" "_rEconcile")
(if (wcmatch (setq test (getvar 'lastprompt)) "*list*")
(command "*" ""); then
(command ""); else
); if
(princ)
); defun
and when I check what that got, it's the latest basic one, including the rEconcile option that the routine gave it:
Command: !test
"Enter an option [?/Make/.../Xref]: _rEconcile"
And yet, by that point in the command, the name-Layers-to-reconcile prompt must have "arrived." I guess I don't understand exactly what the LASTPROMPT System Variable does. Help says:
This string is identical to the last line seen at the Command prompt and includes any user input.
the end of which explains the rEconcile option that the routine fed in being shown there. But the command-line history shows:
Command: RAL
_.layer
Current layer: "0"
Enter an option [?/Make/.../Xref]: _rEconcile
Enter name list of layer(s) to turn reconcile or <select objects> or [?]:
[this would be where the routine is checking for the LastPrompt, but it's feeding in "" instead of what it should: "*" followed by ""]
No unreconciled layers selected.
Enter an option [?/Make...
which indicates that the blue part has been "seen at the Command prompt," because it's the Enter fed in, in response to that, that's causing the line under that. But somehow (getvar 'lastprompt) is not seeing it that way, but is recognizing the next-to-last prompt instead.
I imagine there's a way to get it to "see" the right one, but I haven't found it yet. Maybe it has something to do with the nil return from the first (command) function, but I don't think so, because if I just do this manually:
(command "_.layer" "_rEconcile")
the nil return doesn't affect anything, but it just repeats the prompt:
Command: (command "_.layer" "_rEconcile")
_.layer
Current layer: "0"
Enter an option [?/Make/.../Xref]: _rEconcile
Enter name list of layer(s) to turn reconcile or <select objects> or [?]: nil
Enter name list of layer(s) to turn reconcile or <select objects> or [?]:

All right -- I think I've got it. In testing [but others please test, too], I find that the message that there are no unreconciled Layers does get recognized as the last prompt [why the prompt asking for names when there are unreconciled Layers does not, I couldn't say*]. So we turn it around from the check in my previous routine, and check for that none-to-do message instead, with the 'then' argument being just to close the Layer command, and the 'else' argument being to ask for all to be reconciled and then close it.
(defun C:RAL () ; = Reconcile All Layers
(command "_.layer" "_rEconcile")
(if (= (getvar 'lastprompt) "No unreconciled layers in drawing.")
(command ""); then - end Layer command
(command "*" ""); else - rEconcile all, then end
); if
(princ)
); defun
*EDIT: Maybe the difference is that the message this checks for is "complete" without any User input. In the other approach, since there's a prompt waiting for User input, and the LASTPROMPT System Variable stores the last one including User input, perhaps it doesn't "register" to be considered the last prompt until after User input has been supplied in response to it.
