Re: [Haskell-beginners] consing an element to a list inside a file

ok, looks much easier and works :) But what are now the correct signatures for the function? Normally the "one and only" function should be: readCal :: IO Calendar My function are: readCal = readCal2 datelist and: readCal2 datelist = do... which returns the Calendar (the list of dates) -------- Original-Nachricht --------

ok, now I did it by just calling from the original function by to a new one with an empty list at the beginning.

How can I add the date at the end of the list? By creating a new list from the new date and using concat or is there a simpler way?

Better stick it to the front by (:) and reverse the list just before printing.
