Does anyone know what this error message means?

Does anyone know what this error message means and if I need to do anything about it? First time I've seen this. It popped up when I did an XLIST. What is the -s option it refers to?  A search brought up over 33,000 results. I had time to look at about 5 which didn't help.

XLIST is an Express Tools command which is defined in a lisp file. It is also very old so may not recognize the object you selected which threw the error. Do you recall what was selected?

I would say to note the object selected when you get that error and avoid selecting the same type in the future. The error itself isn't hurting anything.

Don't remember what the particular object was. I think it was just an unknown line in an xref. I'll pay more attention to that next time but it hasn't happened again yet. Does the "-s" command suffix it refers to mean anything to you? 

Thanks

Yes, it's just a different method of making command calls within lisp. In this case, AutoCAD thinks that by changing how the XLIST lisp calls commands it may help stop the error.
