too many buffers

[Jack Hokus]

Hi all,

I am beginner in Emacs. I  have this problem. Emacs open up many
unnecessary buffers. I use Emacs to work with LaTeX. My goal is to
have open three buffer, first with .tex file, second with outpot from
program LaTeX and third with completed pdf file. How to do? I was
looking for a solution and found this options (put
'dired-find-alternate-file 'disabled nil) But i  want to disable open
scratch  buffer and set message buffer too to be opened only when the
program crashes. How to do?

Sorry but English is not my native language. Have a nice day
