 Q: I am trying to build a list of statements linked through NEXT CHAIN, but I cannot get it to work. Any ideas about how this process actually works ? In the excerpt below I just call apend_to_statement_list for my two statements. By append's source code, a new statement list should be built bellow mylist if mylist is initially NULL. This partly works, i.e. if I print mylist I can see stmt1 and stmt, but it keeps saying I cannot retrieve them using NEXT CHAIN...
