I have a subroutine: 
sub msg {
    $msg_num = @_[0];
    $msg_txt = "$msg_num $msgs{$msg_num}";
    print "HTTP/1.0 $msg_txt\n";
}

[download]
It accesses this hash: 
%msgs = ("200", "OK", 
         "400", "Bad Request",
         "403", "Forbidden", 
         "404", "Not Found", 
         "500", "Internal Server Error");

If i call it directly from my program... 
&msg(400);

[download]
it works: 
HTTP/1.0 400 Bad Request

[download]
However, if I call it from an if statement... 
if ($proto ne "HTTP/1.0") { 
    &msg(400); 
}

[download]
it doesn't fully execute (the error text doesn't get printed): 
HTTP/1.0 400

Any thoughts?
Thanks
