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
