I don't quite get what you're referring to regarding "Print out Hal's program" Hal's "Program" is an exe file that's over 2 megs long and would really do you no good.
If you mean the conversation that you've had then yes, in the main menu > Save/View Conversation.
Number two, yes you can assess most of those through the use of various Plug-ins that are available here.
I think someone worked on that at one time. Kind of like telling Hal to turn off bedroom light as would a listening device in a home control system (X-10, Insteon, Z-wave), etc. Perhaps some others might chime in here.
You should be able to "Alter" stored info by looking through Hal's Brain at the various Tables where info is stored.
BTW, Welcome aboard!
