Thanks for your replies. Now it is becoming clear to me:
1. The statement net : type_net renames element (n) gives a copy of element (n).
2. After the assignment to "result" (line 55), "result" points to an element inside the local copy "net".
3. Once "net" is overwritten in the next call of query_net, "result" still refers to a "net" that does not exist anymore. Likewise, once procedure query_net is left, "result" still points to a list that does not exist anymore. Thatswhy I get garbage in line 68 and 77.
Correct ?
