in reply to readline() on unopened filehandle

Since you are just a few months into perl, here is the canonical way to do this (Note - I changed the name and meaning of your variable for clarity):

my $pfaminput_filename ='D:/ARP/Downloads/Trembl/toxinpospf.txt'; # Double fwd-slash is not necessary open (my $pfaminput_filehandle , "<" , $pfaminput_filename ) or die "Can't open '$pfaminput_filename' : Error is : $!"; while (my $pfam = <$pfaminput_filehandle>){ print $pfam; } close $pfaminput_filehandle;
Update: Corrected variable name inside error message.

             I hope life isn't a big joke, because I don't get it.
