Passing a Variable or Value to a Subroutine in Perl

To pass a value to a subroutine in Perl:

&gy("Hiya");

sub gy {
print "$_[0]";
}


Which Prints:
Hiya


-We called, or executed, the subroutine gy and passed the value Hiya.
-When a subroutine is called, whatever is inside the parenthesis is accessible in the built-in variable $_[0]
-In our subroutine gy we said to print whatever is passed to it.



Copy and Paste Perl Code:

#!/usr/bin/perl

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

&gy("Hiya");

sub gy {
print "$_[0]";
}

exit;
