A few question regarding DDB

[Eax Melanhovich]

Hello

I'm learning DDB and here are a few things I still can't figure out:

* Is it possible to show procedure arguments and local variables?
* Can I see source code that correspond to the current eip value? Or at
  least assembly?
* Can I switch between different threads?
* How about different stack frames?

Perhaps answers to these questions are somewhere in `help` output or in
man pages but I didn't managed to find them. So I would appreciate your
help.
