Dialogue problem : make a dialogue with animations

[esp]

Hello , I'm endrit and i need some help with dialogue , or how to use in the best way strings and code ! I've looked on the net but really i didn't find nothing wich explain or helped me with this .
I've used the Adam Gledhil's tutorial on dialogue and with some modifications it works quite good !

The problem is oh how to make a real "multi-persons" dialogue ! I have string in the ini file that i extract i need to find a way to identify when the string is sayed by the pg or by png .
Id like to use animation according to which one is talking .

I find this link http://www.create-games.com/forum_post.asp?id=294754 , is interesting what "The_antisony" has written but i really do not understand the code ,

Right$(CurLine$( "Get Line" ), Len(CurLine$( "Get Line" ))-5)

what is the function of "CurLine$" , "Len",Right$ and every other things that finish with "$"

Reading what he writted down (let's say what I understood becouse I'm not british/american) it is possible to use some kinde of tags like in html to identify which one is talking ! And it's possible to avoid to make apear that part (tag) in the displayed string !

Please help me , I really have no idea on how to get working this !
Sorry for my horrible english , i live in italy !
