LISP to automatically load groups of linetypes.

Somebody help me fix my code. Please!

(defun C:llt()
(command "-linetype" "l" "cen*" "acadiso.lin" "")
(command "-linetype" "l" "hid*" "acadiso.lin" "")
(princ)
)

...working on it and this is what I've got. It seems to work fine.

Any suggestions?

(defun c:llt()
(setq a "Center")
 (if (= (tblsearch "ltype" a) nil)  
      (command "-linetype" "l" a "acadiso.lin" "")
            (princ))
(setq b "Center2")
 (if (= (tblsearch "ltype" b) nil)  
      (command "-linetype" "l" b "acadiso.lin" "")
            (princ))
(setq c "Centerx2")
 (if (= (tblsearch "ltype" c) nil)  
      (command "-linetype" "l" c "acadiso.lin" "")
            (princ))
(setq d "Hidden")
 (if (= (tblsearch "ltype" d) nil)  
      (command "-linetype" "l" d "acadiso.lin" "")
            (princ))
(setq e "Hidden2")
 (if (= (tblsearch "ltype" e) nil)  
      (command "-linetype" "l" e "acadiso.lin" "")
            (princ))
(setq f "Hiddenx2")
 (if (= (tblsearch "ltype" f) nil)  
      (command "-linetype" "l" f "acadiso.lin" "")
            (princ))
(princ)
)

Too much exatra code:

(defun c:llt()
 (foreach lt '("Center" "Center2" "Centerx2" "Hidden" "Hidden2" "Hiddenx2")
   (if(not(tblsearch "ltype"lt))
     (command "_.-linetype" "_l" lt "acadiso.lin" "")
     ); end if
   ); end foreach
 (princ)
 ); end of c:llt

Thanks, ASMI!

this could help if you want to add some words to lines. not sure how to shorten second dot if word is shorter than 3 letters i think it puts def in folder than you edit from there .

I have tried your code JOINTHEPOPE but it didn't give what I wanted. I don't know if its just that I don't know how to use or what, but its not working. Anyway ASMI's code is good enough.

Thanks for the effort.

Ya, that guys the king
