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.

[marioroy]: If yes, for redirection to work, one might do the following
[marioroy]: `bash -c "clang --version 2>/dev/null"`
[choroba]: Sane people don't use csh
[marioroy]: the 1>&2 will work, not shown
[marioroy]: sorry, did not know which if cmd.exe or unix (bash)
[choroba]: csh considered harmful
[erix]: no, I'm using bash :)
[marioroy]: :)
[marioroy]: I use the default and happens to be bash
[erix]: heh, I like the "Resolved" (Christiansen is really funny)
