What language should I learn

Hey /prog/ I'm wondering what ENTERPRISE language to learn in order to get a job. I know C if that helps.

Not completely so, particularly because functions aren't an assignable and passable data type, but it uses many of the same principles, i.e. the output is the result of various transformations of the input. However: http://fxsl.sourceforge.net/articles/FuncProg/Functional%20Programming.html
