a couple of questions from a newbie

[sybershot]

first I would like to say wow, ultra hal is the greatest. I have been using hal for about 2 weeks, and I loved it so much I purchased it. I wish I found out about hal sooner

my first question is: I'm new to building flash web sites, and was wondering if I could have hal remember how to construct a function?
small scale example
how do I build a function: stop
reply from hal   stop();

my second question is: how can I have hal read something, like a kids book, and have hal teach my kids about it? or talk about the subject with them?
