Is there any way to prevent a line break in HTML? For example, on one of my web pages the browser put a break after the comma in the number 43,560. I could remove the comma, but that makes the number harder to read.
I seem to remember old-style HTML has a way to prevent line breaks but it isn't universally supported and isn't legal in stricter varieties like XHTML.

<NOBR>tag, but you should use Johannes's answer below. – T Pops Nov 20 at 17:25
