Hi erum,

The code you provided is working well, so i guess your requirement is actually about the ealier thread you posted, right?

If so, you can achieve this goal with the $controllerProvider.allowGlobals() to set the controller be used global.

You can refer to Using ng-app without a value, in this thread, it's mentioned that you can use the global controller before Angular 1.3, but in 1.6.4, the $controllerProvider.allowGlobals() is needed.

Also please check AngularJS, allowGlobals for global controllers about how to use this statement.

In your case, you can update your code like this:
```
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <meta charset="utf-8" />
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
    <script>
        angular.module("ng").config(function ($controllerProvider) {
            $controllerProvider.allowGlobals();
        });
        function FunctionHelloworld($scope) {
            $scope.message = "ERum";
        }
    </script>
</head>
<body>
    <div ng-app ng-controller="FunctionHelloworld">
        Hello:
        {{message}}
    </div>
</body>
</html>
```
However, this $controllerProvider.allowGlobals() is generally not recommended because of namespace related risk.

Best Regard,
