STDOUT

The special filehandle for standard output in any package.

DATA

The special filehandle that refers to anything following the _ _END_ _ token in the file containing the script. Or the special filehandle for anything following the _ _DATA_ _ token in a required file, as long as you’re reading data in the same package _ _DATA_ _ was found in.
