Try this: let b = if a == True then "+" else "-" in ...

Hi,
I'm sorry because I am absolutely sure, this is bloody obvious to the knowing. Being a total beginner I'm stuck. In the main = do part I wrote:
1: if a == True then putStrLn "Yes!" else putStrLn "No." 2: if a == True then let b = "+" else let b = "-"
Line #1 works perfectly well. Read line #2 as pseudocode and you'll see what I want to do. Read it in ghci and it produces " parse error on input `=' "
I tried 'case of' but it doesn't work either.
What am I doing wrong? Thank you for any help,
Bernhard
