Document mismatch problems with SDI=0 mode

Hi Everybody,

I am new to SDI=0 mode. I never had to use it before, but now I have to
because I am starting to use Sheet Set manager.

Now I am having a problem with a couple of the programs which I have
loaded in my Startup Suite.
(programs that always work in SDI=1 mode).

When I try to use one of these lisp routines that use the "vlax-add-cmd"
function, after I've opened the first dwg (it works), then opened the second
dwg (it works), then gone back to the first dwg, I get this when I run it:


****************************************************************************
******
Command: 'zq
; error: Visual LISP command document mismatch: ZQ
****************************************************************************
******

I have tried both settings of the "load acad.lsp with every drawing"
checkbox in Options, but it has no effect on this problem.

Here is the code for the 2 I'm having problems with:

note: this code preforms a neat transparent zoom window command
----------------------------------------------------------------------------
-------------------
(vl-load-com)
;; Zoom Quick Window (Command "ZQ")
(defun agc-zq (/ ll ur pt)
(setq osm(getvar "osmode"))
(setvar "osmode" 0)
(setq ll (vlax-3d-point (setq pt (cadr (grread nil 1)))))
(setq ur (vlax-3d-point (getcorner pt "\nPick Second Corner:")))
;;;;;;;;;; ; (vla-zoomWindow *agc-acadobj* ll ur)
(setvar "osmode" osm)
(vla-ZoomWindow (vlax-get-acad-object) ll ur)
(princ)
)
;(agc-zq)
(vlax-add-cmd "ZQ" 'agc-zq "ZQ" 1)
----------------------------------------------------------------------------
-------------------

note: this program toggles running osnaps
----------------------------------------------------------------------------
-------------------
(vl-load-com)
(defun TGL (/ A)
(SETQ A(GETVAR "OSMODE"))
(IF (/= A 0)
(SETVAR "OSMODE" 0)
(SETVAR "OSMODE" 41) )
(princ)
)
(vlax-add-cmd "TGL" 'TGL "TGL" 1 )
----------------------------------------------------------------------------
-------------------

(I think it was Phil Kennewell (spelling?) who kindly gave me the code 5
years ago).


Document mismatch problems are over my head. Any suggestions are greatly
appreciated.
