poj has shown you how to open a normal file. The previous code that used `DATA` is using the special filehandle `DATA`, which reads from beyond the `__DATA__` marker, as if it were a separate, already-opened file. For more on the `__DATA__` special literal, and the automatic `DATA` filehandle, see https://perldoc.perl.org/perldata.html#Special-Literals edit: clarify	[reply] [d/l] [select]
