annotating line entities

Need help,

I found this program that does pretty much what I need it

to do, but I would like it to use the current text style instead

of using "standard" and more importantly I need it to put the

text at the "midpoint" of the line or lines either above or below.

Thank you much

(defun c:LINELENGTH ( / CONST_STYLE CONST_TXT-HT CONT COUNT DIST ENT IP LAYER ROT SS)
(if (setq ss (ssget))
(progn
(setq count 0)
(repeat (sslength ss)
(setq cont (entget (ssname ss count)))
(if (= "LINE" (cdr (assoc 0 cont)))
(progn
(setq CONST_txt-ht 1.0
CONST_style "LY080"
layer (cdr (assoc 8 cont))
ip (cdr (assoc 10 cont))
rot (angle (cdr (assoc 10 cont)) (cdr (assoc 11 cont)))
dist (distance (cdr (assoc 10 cont)) (cdr (assoc 11 cont)))
ent (list
(cons 0 "MTEXT")
(cons 100 "AcDbEntity")
(cons 8 layer)
(cons 100 "AcDbMText")
(cons 10 ip)
(cons 40 CONST_txt-ht)
(cons 41 dist)
(cons 71 7)
(cons 72 5)
(cons 1 (rtos dist 2))
(cons 7 CONST_style)
(list 210 0.0 0.0 1.0)
(cons 11 (cdr (assoc 11 cont)))
(cons 50 rot)
(cons 73 1)
(cons 44 1.0)
)
)
(entmake ent)
)
)
(setq count (1+ count))
)
)
)
)

Are you interested in learning how to edit the code or is this a request for someone to do it for you?

Preferably I would want someone to code it for me.

If that is possible.

Thanks
