I am not sure exactly what you want to do.
Do you want to change the contents of a string (up to a point)? In
that case, you can't. Javascript strings are immutable. You have to create
a new string, e.g.:
str = "dummy string";
str = "new prefix "+str.substring(6);
alert(str); // alerts "new prefix string"
Get it into a variable? I can't guess that one.

Sure you can. :)
str="new prefix";
myNewVar = str.substring(4);
myNewVar is now "prefix".

fv = document.title.substr(0,20)
But I want to find @ in document.title
And put that part of the string in fv

Which part of the string? The part from 0 to '@' or the part from '@' to
the end?
Inclusive or exclusive of the '@'?

Use the subtr method:
<SCRIPT LANGUAGE="JavaScript1.2">
str = "abcdefghij"
document.writeln("(1,2): ", str.substr(1,2))
document.writeln("(-2,2): ", str.substr(-2,2))
document.writeln("(1): ", str.substr(1))
document.writeln("(-20, 2): ", str.substr(1,20))
document.writeln("(20, 2): ", str.substr(20,2))
</SCRIPT>
This script displays:
(1,2): bc
(-2,2): ij
(1): bcdefghij
(-20, 2): bcdefghij
(20, 2):

fv = document.title.substring(0,document.title.indexOf( "@"))
Note on substr/substring: substr() has two arguments - the start and the
length. substring() has two arguments - the start and the end.

That works perfect, thanx !

Let the character be #, and the string example be S = 'abcd#xyz'
S.replace(/#.*/, '') // -> 'abcd'
S.replace(/.*#/, '') // -> 'xyz'
OK = /(.*)#(.*)/.test(S)
// RegExp.$1 = 'abcd'
// RegExp.$2 = 'xyz'
