AS small alphanumeric signs

[tigger]

Would you mind making a "schematic" or a Picture.
I do not get it.

Imagine I have stairs. The top stair is A, the next below is B and the bettom is C. Every stair should equal to a subdirectory. On every step you can find a variable. Imagine I am on the stair A and I look down.

On step A there is x.
On step B there is y.
On step Cthere is z.
Which variables do I see.

Imagine I am on the stair B (or in the subdirectory B) which variables do I see if I looked down (in the subdirectoy C) which variables do I see if I looked up.

Imagine I am on the stair C (or in the subdirectory C) which variables do I see if I lookel up (to the subdirectory B and then to the subdirectory C).

You might have a better example besides stairs?

Besides you might tell me how to send Pictures. I could exlain my Problems better with Pictures.
