Layer list with the description column

[teknomatika 10]

I have this routine (unknown to the author), which lets you export to a text file the list of existing layers in a drawing. It works fine, but I wanted a version that could include one column for the description of each layer.

Thank you in advance for your possible help.

oecho (getvar "cmdecho")
clrlst (list
(cons 1 "RED")
(cons 2 "YELLOW")
(cons 3 "GREEN")
(cons 4 "CYAN")
(cons 5 "BLUE")
(cons 6 "MAGENTA")
(cons 7 "WHITE")
)
dwgnm (getvar "dwgname")
)
(setvar "cmdecho" 0)
(setq fn (getfiled " File name: " (strcat dwgnm ".LS") "LS" (+ 1 2))
)
(while (setq lyr (tblnext "layer" (not lyr)))
(setq lyrlst (cons (cdr (assoc 2 lyr)) lyrlst))

(setq lyrlst (acad_strlsort lyrlst))
