Neil,
Basically in this example i would like to return the value 4
type Bob = [(Int, Int)] newLine :: Bob newLine = [(1,4)]
i have tried to use the follwing but it returns the error below it.
newLine !! 0 - (so that should give it the newLine list and try and return the 1st element of the list)
the error reads thus
ERROR file:.\VicotriaLine.txt:107 - Type error in final generator *** Term : newLine !! 0 *** Type : (Int,Int) *** Does not match : IO a
Instruct the interpreter to print it: print (snd (newLine !! 0)) HTH, Stefan
