Landing Distance (MULTILEADER)

Im looking for a lisp routine or variable that will uncheck the highlighted "Set landing distance" without opening dialog box? Is there a chance to do that? Thank you in advance.

Consider the following function:

(defun MLeaderLandingDistance ( sty flg / dic )
   (and (setq dic (dictsearch (namedobjdict) "acad_mleaderstyle"))
        (setq dic (dictsearch (cdr (assoc -1 dic)) sty))
        (entmod (subst (cons 43 ((if flg + -) (abs (cdr (assoc 43 dic))))) (assoc 43 dic) dic))
   )
)

The above function requires two arguments: the MLeader Style to be modified and a boolean argument to determine whether the Landing Distance should be enabled or disabled.

For example, to enable the Landing Distance for the current MLeader Style:

(MLeaderLandingDistance (getvar 'cmleaderstyle) t)

And to disable it:

(MLeaderLandingDistance (getvar 'cmleaderstyle) nil)

Perfect This is exactly what im looking for. Thank you very much Lee, now my code is working great..Cheers!

You're welcome!

My problem is how the landing distance gets randomly changed. Even though it is defined as 1/8" there are times that it gets changed to something like 19/32" and causes the landing to run into the text. Its easily fixed by selecting all and reapplying the 1/8" but its still annoying to see a leader running thru your text when you plot. This is indeed a bug that has never been addressed as this has been going on for several releases of AutoCAD over the past several years. Multi-Leaders are very handy but this bug is annoying.
