Hi J,

I think we'll have to check some terminology here.

I assume with "a clean menu with the 7 numbers on the left" you mean
the stack display. If your calc is in RPN mode you can always get
there by pressing ON (repeatedly if needed). You can clear out any
numbers/items there with CLEAR (RSHIFT <=).

The HOME directory is the basic place to put variables etc. On the HP
calcs the Memory is organized in a Drive/Folder structure, much like
on a desktop computer. You can have a look at it with the file manager
(FILES).

In general: with the HP49(+) HP introduced some features to help
novice users, namely Algebraic mode and Choose Boxes.

The first everybody should abandon immediately. The HP command set and
interface are just not built for it, and it will slow anybody down.
Learning RPN is a matter of minutes, mastering it a matter of
practice. When you see it creep into how you view formulae (i.e.
inside-out), you will know you're there. It's worth it.

Choose Boxes (i.e. the full-screen menus popping up all the time) are
a great way of learning your way around the (admittedly sometimes
confusing) menu structure. Once you get to know which-is-which and
what-is-where you can speed up your work considerably by changing flag
117 to Soft MENU. Then most menus will only use the keys A–F (try it
out, you'll see). They no longer obscure the stack, allowing you to
work much more fluently, especially if you often need several items
(units, commands…) from the same or "close" menus.

Have fun, M.

PS: please DON'T YELL!!1!

a question: HOW DO I GO BACK TO THE HOME MENU when I am stuck on some
other manu? To make it clear: I want to find which key or combination
will clear the screen and put me on the home menu. I often get stuck
and spend half hour to get back to a clean menu with the 7 numbers on
the left and start over. There has to be a way. On the Ti-84 I used to
have you could always go back to "home" very easily. Please help!
