<P>Expressions are FunnelWeb's most powerful form of
expressing a text string. Macro bodies are defined as
expressions. Actual parameters consist of expressions.
<P>An expression consists of a sequence of zero or more
expression elements. An expression element can be ordinary
text, a macro call, or a formal parameter of the macro
<I>definition</I> in which the formal parameter occurs.
<P>
<PRE>
expression = { ordinary_text | macro_call |
formal_parameter }
