Because the compiler thinks that you are probably doing something pointless. You are loading a filehandle, but never accessing it. Since it can't see why you would be creating a filehandle without using it, iot guesses that you may have mistyped some other name. > When i remove the warnings,this goes off? > Is there any problem if i not include "use warnings" line? Better to either do something with the filehandle, or get rid of it. Don't shoot the messenger.
