What are 'mode' and 'coding'?

What are 'mode' and 'coding'?

[Leo]

Hi there,

One can write "-*-mode:emacs-lisp;coding:utf-8;-*-" on the head of a
file to force emacs to use emacs-lisp-mode and utf-8 coding. I am
wondering what are `mode' and `coding'. I use 'C-h v' on them and
there are no such variables.

Thank you for your help.

It's major-mode and buffer-file-coding-system.

Thanks for your answer.

Are there any other such variables other than 'mode', 'coding' and
'eval'?

Please have a look in the Emacs info system:

C-h i g

Then type this

Mode is the Major Mode that the file opens to when it is visited in
Emacs.

Coding is the encoding on the file, ie. UTF-8, Latin1, etc...

See the node "File Variables" in the Emacs manual, it explains all
that.

Look for buffer local variables.

For the record, there are altogether 4 pseudo variables i.e. mode,
coding, eval and unibyte.
