It's a typo in ikegami's code. Change line 3 to:

use warnings;

    haha, yeah! didnt even notice!
    anyway, the code still doesnt work. i just get an error saying that:
    syntax error at output.pl line 2, at EOF Execution of output.pl aborted due to compilation errors.
    this is the exact code that im running:
    #!usr/local/bin/perl use strict; use warnings; my $output = "data"; my $out; for (;;) { print("Do you want to output to (S)creen or to (F)ile? "); chomp( $out = uc( <STDIN> ) ); last if $out eq 'S' or $out eq 'F'; print("Invalid input. Please type either S or F.\n"); } if ($out eq 'S') { print $output; } else # $out eq 'F' { for (;;) { print("Please enter filename: "); chomp( my $save = <STDIN> ); if ( $save !~ /^[a-zA-Z][a-zA-Z_0-9]*\Z/ ) { print("Invalid input. Please begin with a letter and do no +t add extension, it will be added automatically.\n"); redo; } $save .= ".ext"; if ( -e $save ) { my $overwrite; for (;;) { print("Filename exists. Overwrite? (Y) or (N) "); chomp( $overwrite = uc( <STDIN> ) ); last if $out eq 'Y' or $out eq 'N'; print("Invalid input. Please type either Y or N.\n") } redo if $overwrite eq 'N'; } open( my $fh_out, '>', $save ) or die "Unable to create $save: $!\n"; print $fh_out $output; last; } }

      That's strange, I just copied and pasted the code and I don't get that error message at all!

      However, there is another mistake in the code, in the block that starts with:

      if ( -e $save ).

      the line that says:

      last if $out eq 'Y' or $out eq 'N';

      should of course read:

      last if $overwrite eq 'Y' or $overwrite eq 'N';

      Once that is corrected, the code works perfectly on my WinXP machine.

        could it be because im running on a mac? os x 10.4
      #!usr/local/bin/perl
      Should be
      #!/usr/local/bin/perl
      (Or wherever you have perl installed)
        this is really strange... i just ran the script on a windows machine and it doesnt work. i just copy and pasted too! why wont the script work???
