Inside a markup tag, like <A HREF="img.html">IMG</A>, A (anchor), or any

other standard HTML or htp tag, the '$' operator should be used. The '$'

should be immediately followed by the macro name, which may or may not be

surrounded by curly braces.

<P> The tagName macro can contain any tag name, even a self-defined
