Your questions are focusing on HOME variable setting. The best answer I can think of is to direct your attention to:

[Help] | Tree | Variables | Home Variables | Home Settings Variables.

You can see which are available, and setting them programmatically, or via the command is generally possible. The entry modes use the "Entry" Home variable.

As Joe has pointed out in another post today, there are some things that need to be considered between the HOME and CAS views.

As far as programming is concerned, jump in! Make a few mistakes, and you'll be much more comfortable with programming before long.
