LISP not loading

Help!

I can't get a certain lisp routine to load via a macro. The other routines I
have work fine, so I'm at a loss to find the problem.

Here's the macro:
^C^C(if (not c:NZX)(load "NZX.lsp"))
NZX^C^C_select;!NZS;;_mirror3d;p;;0,0,0;0,1,0;1,0,0;Y;

Here's the routine:
(defun c:NZX () ;Negative Z eXtrusion
(setq nzs (ssadd))
(setq a (ssget "X"))
(setq b 0)
(repeat (sslength a)
(setq c (ssname a b))
(setq d (entget c))
(setq e (cadddr (assoc 210 d)))
(if (equal e -1.0 0.000001)
(setq nzs (ssadd c nzs))
)
(setq b (1+ b))
)
(setq nzslength (sslength nzs))
(princ "\nThere are ")
(princ nzslength)
(princ " entities with -1 Z-extrusion in this drawing.")
(princ "\nThat selection set is named !NZS.")
(princ)
)

The lsp file is in the support directory, and the whole thing works fine
when loaded from VLISP. I just can't get it to load via the macro.

Thanks

 

I just looked quickly on screen, but I think it might be the ! in front of
the NZS

 

If it's just not loading the lisp file, try this:

Code:

^C^C(if (not c:NZX)(load "NZX.lsp"));NZX^C^C_select;!NZS;;_mirror3d;p;;0,0,0;0,1,0;1,0,0;Y;

It's got to be a problem with the macro. Take it apart and find the part
that's broken.

I don't like having a menu cluttered up with multiple lines of "(if (not
c:whatever)(load "whatever"));whatever;" where the only thing that varies is
<whatever>, and the if test gets performed every time the macro is run.

You can eliminate all of this by loading the lisps in an associated mnl
file. The intent of mnl's is to get much of the inline lisp out of the menu,
and to ensure that any lisps used by the menu are available.

If your mnl contained the line (autoload "nzx" '("nzx")), then your menu
macro could simply begin with ^c^cNZX.

 

I was not aware of the mnl file. That solved the problem. Thanks Tom.

The mnl can have lots of handy uses, since it loads automatically along with
the associated menu. We use a custom partial menu, and when it loads the mnl
initializes all of our other customizations. It can serve the same purpose
as an acaddoc.lsp file.
