<P> Function calls of the form <TT> (function & nbsp;arguments) < /TT > or < TT >function arguments</TT> will be processed differently than a normal macro expansion. A function call acts like a macro expansion in that it returns a string. All spaces, except for the sequence of spaces before the first argument (after expansion), are significant.
