IBIS: Making, lines, symbols...

Hi there !

Yesterday I build a new line, called "13N". I made the Tracks & Trips, everything is fine, no errors etc. But, when I'm at bus i'm typing the following code:

Linien/Kurse: 91304
Ziel: 212

I have some questions:

1. How can i know the IBIS code for given line ? (ex: 2A, 35V, 63N. 21A, 10F) etc..
2. How can i made the route 01/02 03/04 to work? Where and what i have to change?
