Providing html rather than a URL to a webviewer

I tried the webviewer example to make a simple web browser. This went OK. I then tried string concatenation so I could omit the http:// portion of the URL, and was able to make that work too. So I have two questions:

  1. is concatenation only for strings or can I concatenate text variables too using the same syntax?

  2. Suppose I have some html in a string (or text) variable. Is there a method which would allow me to have that rendered by a webviewer?

See http://documentation.xojo.com/index.php/HTMLViewer.LoadPage

Thanks. I did eventually find the answer, but then had trouble making it work as it needed a second parameter. Still finding my way around the documentation.
