in reply to Seeking a better way to do it

What is your rule for extracting 'Iago' and 'Othello'? Do you also mean to extract 'Enter' (another word that starts w/ a cap)?

You said your solution works, but you write plit instead of split and I get other errors. Can you update it with functional code?

    I think the OP meant 'Iago' and 'Othello', so maybe something similar to this: 
    #!/usr/bin/perl -l

use strict;
use warnings;

my ($char_list) = "Enter Iago, Othello, and  others";

my (@words) = split( /\W/, $char_list, 0 );
foreach my $word (@words) {
    if ( $word =~ m/[F-Z]\w+/g ) {
        push my (@entering_chars), $word;
        print "@entering_chars";
    }
}

      But starX's script also gives "Enter" word in the output. I guess he/she need to extract words contains Upper case letter

      Ya, we really need more info. Limiting the first letter to F through Z is not very portable. If you already know the words you want (and choose the letters accordingly), you might as well name the words specifically.
