Can anyone tell me why I'm getting this error on just a simple lisp?

Command: KA
Unknown command "F". Press F1 for help.
Unknown command "*KEYPLAN|*PATT-*". Press F1 for help.
Unknown command "KA". Press F1 for help.
Unknown command "F". Press F1 for help.
Unknown command "X*|S-GRID*MAT**". Press F1 for help.
Unknown command "KA". Press F1 for help.
Unknown command "T". Press F1 for help.
Unknown command "*KEYPLAN|*PATT-A". Press F1 for help.
Unknown command "KA". Press F1 for help.
Unknown command "T". Press F1 for help.
Unknown command "X*|S-GRID*MAT*-A". Press F1 for help.
Unknown command "KA". Press F1 for help.
Unknown command "T". Press F1 for help.
Unknown command "*KEYPLAN|*PATT-NOTE". Press F1 for help.
Unknown command "KA". Press F1 for help.

THIS IS THE CODE FOR KA.LSP
[CODE]
(defun c:KA ()
(command "layer" "f" "*keyplan|*patt-*" "")
(command "layer" "f" "X*|s-grid*mat**" "")
(command "layer" "T" "*keyplan|*patt-A" "")
(command "layer" "T" "X*|s-grid*mat*-A" "")
(command "layer" "T" "*keyplan|*patt-NOTE" "")
(princ)
)
[\CODE]

I'm not an expert on LISP code (yet), but from what I can tell, your code looks fine.

Are you sure the routine is being loaded?

I loaded and executed the code you pasted on my system and the only errors I get are "No matching layer names found", which was expected. I suggest verifying that your code is loaded.

Good Luck!!

Just another thought, but I was looking at your code and noticing that it is calling the layer command 5 times when it could be calling it once. I'm not sure if you have a reason for that, but I do know that it is more efficient to open with the LAYER command, process everything, then close it.

Here is a more efficient version of your code (for anyone interested):


(defun c:KA ()
 (command "layer"
            "f" "*keyplan|*patt-*" 
            "f" "X*|s-grid*mat**"
            "T" "*keyplan|*patt-A"
            "T" "X*|s-grid*mat*-A"
            "T" "*keyplan|*patt-NOTE" "")
(princ)  
)

You didn't redefine the layer command did you?

When I type in "layer" it pulls up the layer dialogue box.

It's killing me that my lisp routine is not working!!! Sorry, just a little frustrated. Hopefully someone had the same problem and could help me.

just out of curiosity, have you tried using "-LAYER"?

Also, have you tried entering each line directly into the command line to see if you get the same error?

For instance:

Command: (command "layer" "f" "*keyplan|*patt-*" "")

Thanks - that was from my old days. I guess I never really noticed it.

This is what I got...

Command: (command "layer" "f" "*keyplan|*patt-*" "")
Unknown command "F". Press F1 for help.
Unknown command "*KEYPLAN|*PATT-*". Press F1 for help.
nil

Do you suppose the autocad utility is not being loaded..?? Like acaddoc.lsp, etc..??

Odd. It's like it's passing right over "layer" and assuming "f" is the command.

What version/flavor of AutoCAD are you using?

Looks like the LAYER command is undefined or redefined. Try:

(command "_-layer" "_f" "*keyplan|*patt-*" "")

(command ".layer" "_f" "*keyplan|*patt-*" "")

Thanks. That fixed it. I'm not sure why it's acting up now though because it's worked in the past before. Perhaps there is a system variable change that causes me to use this layer command format...?

The layer command was undefined after all? Who would have guessed? LOL
