Where do you set your right margin?

Where do you set your right margin when coding? To put that
another way, if you have a long line of code, how long would it have to
be for you to break it up into multiple lines. Obviously, sometimes you
break even a small line for readibility. But other times, you'll
have just a really long line of code that's all one statement. Do
you have any rules for when to break it? I'm thinking that 105
characters is about right.

I use 120 - 160 if i'm not planning on accessing it on
a terminal so that i can keep SQL queries in a single line ( e.g. "DELETE FROM
id= '$id' LIMIT 1" ).
Generally 80 is the most common for historical reasons ( 80*24

I never, ever go past 80 columns. It doesn't matter how wide my screen
is. Long lines are always a chore to read, be it plain text or source
As for where I break long lines, I have a simple rule: on a line like:
long_variable_name = long_function_name(long_argument1, long_argument_two);
I either break like that:
or like that:
long_variable_name = long_function_name(
if the first version doesn't fit whithin the margin. If I have a really
long expression involving other operators than assignment, I break
before an operator.
It's not very uniform, but it makes the most readable code, IMO.
I keep long lines as long lines mostly, since breaking them up usually results in less legible code.
Except where not. It really all depends on the situation. There is no correct maximum line length.
I add/subtract several things in onse statement, I usually do this syntax:
[code]var bladibla = getWidth('something')
Same goes for concatenating bits of string, such as long SQL statements:
var foo = 'sdkjs ,ksb slvk el'
+ 'zsdm,vhjybsdvilblbvil sb l '
+ 'xvsdkgs elvisuhvlsuihodigei'
The separations aren't arbitray, of course, and not based on some random character count. I'm not sure, but mabye I or someone should do a benchmark to see if the [+] method is faster to run than the [variable +=] method. May not differ much anyway, though the +'s can easily be compiled away.
this is a test to see if I can use a TAB inside the [ code ] tag.
