[PD] line~ segments

I am trying to test your segtest patch of lineseg~. Once I load the numbers (either with the middle or right message boxes) and press bang I am only getting the print 
statements out (the numbers seems ok) but nothing from the line~ itself comes out. Looking into lineseg~ I wonder if you can just connect the output of a textfile to the 
inlet of a line~ object. I don't understand why this should work. If this is supposed to work why a sequence of number pairs, delimited with commas shouldn't?

So, I am not seeing anything on the db display or on the lineout array. I also

Please tell me if I am missing something.

So my mind was playing tricks on me: I have never used Max/MSP.

That's a good idea, but in fact it was a bit trickier to realize than
I first thought. I got it working and as I think that this is a very
useful abstraction I attached a "lineseg~", that can be used just like
the Csound opcode or as a simple ADSR.

It would be trivial to extend it with a note-off sensor and an amplitude
scaling factor if one replaces the trigger bang with float messages and a
[select 0].
