Calling a function in Haskell - beginner problem?

Yes, you need to hook it up to your main function. For example.

A Haskell source file contains a sequence of definitions, not expressions. So you can't just put an expression in the top level of the file, you have to put it inside the body of a definition. So since pe 1000 is not a definition, you get an error.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
