Try this after your move command so you can see your text as you move it about
(setq pt1 (cdr (assoc 10 (entget(entlast)) )))
pt1 is the text coordinates.
I've not seen how to hide that dashed line as you move things, is it a big problem or something that would be nice? If you can hide it, I guess it will be a system variable to change, type setvar and then ? to see a list of them, might be in there but I don't know
