How to read a Adjacecny list from a text file

[Hossein Dashti]

I was wondering how can I read a data file in AMPL where number of rows is known nut number of elements per rows are dynamic and changes per row?
Say, I want to read following adjacency list:
1 2 4
1 5
4 8 9 12
1 3

It depends on how the data is defined in your AMPL model. If you can show the AMPL set and param statements that you want to use for this data, then it should be possible to give a specific suggestion for reading this file.
