I used C quite extensively in the early 90s for systems programming tasks, and to model our mortgage payments after the building society had made an enormous cock-up and offered derisory compensation. I haven't touched it since I discovered that Perl could do the same job in a fraction of the development time. Thank you for the suggestion, I might well do some C revision to see if I can get back up to speed.

Sadly, the song video seems to be unavailable so I might remain irrelevant for a bit longer :-(
