Fortran.
isn't it supposed to be capitalized? like: FORTRAN?
Doesn't look like it is lately, though, sorta like how it's Visual Basic, and not Visual BASIC probably... more a display thing.
Like many languages there is even a compiler for FORTRAN that compiles to CLR IL:
http://www.mpassociates.gr/software/distrib/science/lahey/lfnet.htmlThen again, there seems to be a .NET compiler for almost any language these days. this one seems to actually boast integration with Visual Studio, which is not as rare as just being tossed the compiler and told to figure it out like for some other CLR languages.
For me, I have no favourite language. There are languages I know inside and out- like VB6, those that I am strong with, but wouldn't go so far as to say I know inside and out C#, F#, Java, VB.NET, Javascript, VBScript, PHP, XAML (if it counts)) those I can use effectively with enough time, (C++, C, Python, Perl, a few others), and then there are the rest.
