What will happen if we don't localize variables to get these removed from memory?

[@cyberCADsolutions]

Memory exploitation

[@ifty_arain]

Thanks for reply. I asked above bcoz autoCAD was getting freeze. So apart from memory exploitation there is no any harmful effect if we don’t localise variables

[@ifty_arain]

Just wana to say thanks, I am really learning well by watching your videos . Is there any full playlist for VLA as I am more interested to learn how to export coordinates from AutoCAD to excel.

Hello. Made according to your example, what could be the error (assign the Z coordinate from the text content)?
(defun c:text_to_z()
(if (setq tset(ssget (list (cons 0 "*text"))))
(progn
(setq n (sslength tset)
counter 0
)
(while (< counter n)
(princ "
...in process")
(setq txt(ssname tset counter))
(setq txtData (entget txt))
(setq newZcoordinate (cdr (assoc 1 txtData)))
(setq newTxtData (subst (cons 30 newZcoordinate) (assoc 30 txtData) txtData))
(entmod newTxtData)
(set counter (1+ counter))
);while
);progn
);if
(princ "
...done")
(princ)
);end
