Hi Robert
(I think I know enough haskell to answer this, but I may be telling you all the wrong things.)
Why? What's wrong?
You'll have to pass the values through, though this can be hidden to some extent. Try changing your functions to have types
type Input = (Float, Float, ...) type Output = (Float, Float, ...)
inputvalues :: IO Input -- add a "return (ve,de,...)" to the end compute :: Input -> Output
How can I combine several function (calculations) in this function?
outputvalues :: Output -> IO ()
You could then wrap them in
main :: IO () main = do input <- inputvalues outputvalues (compute input)
This should do what you want.
Thank's for your hints.
It might be improved upon by using data types with appropriately named fields instead of tuples so as to keep your variable names around.
Can you give me an example how do to it with named fields? Thanks Thomas
