<p>
Especially if you are a beginner, you should place the statements <c> use warnings; </C> and <c> use strict; </C> at the beginning of all your code:
<c>
c:\@Work\Perl\monks>perl -le
"use warnings;
use strict;
;;
use utf8;
;;
my $pi_char = chr(OxO3c9);
print qq{Greek letter '$pi_char' here};
"
Bareword "OxO3c9" not allowed while "strict subs" in use at -e line 1.
Execution of -e aborted due to compilation errors.
</C>
I.e., <c>"OxO3c9"</C> (letter "O" vice decimal digit "0") is not a hex number, as already noted. See [doc://warnings] and [doc://strict].

In other words, "Help Perl to help you."
