burn only a .bin?

[JebJoya]

My friend sent me a rar file with a copy of a program he's been making, and wanted me to have a look, but he only appears to have sent me a .bin file, he's gone off to czechoslovakia for a week, and so I'm stuck.

Of what I vaguely know of CD backups, the actual data is stored in the .bin, so is there any chance he hasn't made a mistake in not sending me the .cue file and I can burn it somehow, or am I going to have to wait for him to get back?

Thanks in advance
