Create a Subroutine in Perl

Creating a subroutine in Perl is fairly easy...

sub gy {
print "Hiya";
}

&gy;

Which Prints:
Hiya


-You can name your subroutine pretty much whatever you like. Here, we named it gy
-We called, or executed, our subroutine with &gy;
-Whenever called, our subroutine will print Hiya

NOTE: We could have placed the &gy; before the subroutine itself and everything would work just as well.



Copy and Paste Perl Code:

#!/usr/bin/perl

print "Content-type:text/html\n\n";

sub gy {
print "Hiya";
}
&gy;

exit;
