You defined the message just before you defined the name, so just do 
#. . . other code that does unrelated stuff . . .
$name = "Larry Wall";
$message = "Hello $name\n";
print $message;

or do like 
$message = "Hello ";
#. . . other code that does unrelated stuff . . .
$name = "Larry Wall";
$message .= $name."\n";
print $message;
