It's an em dash. The spacing conventions depend on the type used. Here, using Courier, I use a space on both sides. Some others don't.

An em rule is a dash, a line about as long as the width of the M character as distinguished from an en rule which is shorter. I would surround them with spaces. The

That's what I'd call an "em dash". I suppose it depends on what font you are using and to which style guide you ascribe. I don't use spaces around them, probably s

Style manuals call for no spaces, but some posters to this group including me think that makes the result look too much like hyphenation. In printed matter, the no-

Thanks for the replies. It looks as if I'm justified in not using spaces if I don't want to. I think things look nicer without. (Sadly I'm also told that I shouldn

Em-dashes require no spaces; some publications, however (e.g., the TLS), use what look like spaced en-dashes.

If you're going to do it, and I agree that it's a good practice in a monospacing environment, you should use two spaces after a sentence, thus: "I went to St. George St. St. John went to West Dr. And Dr. West went to Jill St. John St. in St. John's."

[nq:1]I'm of the generation that doesn't put spaces around dashes, but there is one considerable disadvantage to such a sensible ... funny hyphen, and will tell you that "sentence such" and "one which" in your example sentence are not words in its dictionary..r[/nq]
I tend not to put spaces around dashes, either. I think my reason is that with a lot of text-editing software, there is a chance
