I think what I want is something about as simple as
this. I was in a panic yesterday because I had
bid on that job as a project, rather than on an hourly
basis, and it suddenly occurred to me that I was earning
less as an IDL programmer than I was earning as a tennis
coach. The idea of explaining *that* to my wife left me
in a cold sweat. Sorry for taking it out on the newsgroup. :-(

Cheers,

David
