Oke,

So  In the file I have to load I must put the first 2 lines. And in the prompt I have to do the last line,

Or is there a way I can use all three lines in a file ?

Roelof

You could say:

x = replicate 3 True

or:

main = print (replicate 3 True)

replicate :: Int -> a -> [a] replicate a xs = [xs | x' <= a <--xs]

replicate 3 True

That last line is fine at a GHCi prompt but not in a program.  (Files loaded by ghci are not scripts!  They are treated the same way as program files fed to ghc or runhaskell.) -- brandon s allbery                                      allbery.b@gmail.com wandering unix systems administrator (available)     (412) 475-9364 vm/sms
