Hi,
add
\usepackage{german}
to your document head and use
"s
to generate a ß. If your document is in an other language you can
use the babel package.
Add
\usepackage[german,english]{babel}
instead of
\usepackage{german}
English is the normal style then. If you like to quote german text
you can change the language for a whole paragraph and more with
\selectlanguage{german}
quote some german sentences and switch back to english with
\selectlanguage{english}
Don't forget to switch back.
With the babel package it should also be possible to use
"s
without switching the language. You can type Umlaute with
"a
for ä and so on.
Armin
