Visual LISP, AutoLISP and General Customization

[#1]

We have a lisp routine that places a vertical line in front of text and mtext.  I want to start using the multi-leader command instead of a customized leader.  Can anyone take a look at our routine and offer suggestions on modifying it so it can work with multi-leaders?  The lsp file is attached.

[#2]

replace

(COMMAND "LINE" ....

with

(COMMAND "MLEADER".... or whatever you want to use in place of "line"

[#3]

Should anything be done to the line near the beginning that is listed below?  Should anything about multi-leader be put in there?

(SETQ ITEMS (SSGET '((0 . "TEXT,MTEXT")))); revised to only get text

[#4]

Maybe I didn't make myself clear with my first question.  If I make the change that you suggested, it'll draw a multileader in front of the text and not a line.  I still want a line in front of text, but I want to be able to select multi-leader text as well as text and mtext.
