Need help with Perl

Hello,

I need some assistance, just a question really. I see this line in my coding:

#print SENDMAIL "To: employment\@rrmca.com\n";
pirnt SENDMAIL "To: retroesh\@gmail.com\n"; #test to see #if it can send to gmail

2 questions pop in my head that I need you assistance. One of the questions is, when I see the line:
#print SENDMAIL "To: employment\@rrmca.com\n";
The # sign, does that mean it’s a comment or does that mean it’s a start of a execute or a pointer? Or is it just a commented out, because we want it to send it to employment@rrmca.com which is an email. Then I look at the email that it shows, however its input within the code as “To:employment\@rrmca.com\n”;
I do know that the \n means end line, which is a common c++ ending line, however it’s the email that it shows it as employment\@rrmca.com which puzzles me, is that correct, or does it need to be “To:employment@rrmca.com\n”; ??

I thank you for taking this time to reading my email, if you can get back to me either email or post it

Thank you

Steven B
