Script functions are declared with HTML anchor (<A>) tags:
<A NAME=banner>
<HEAD><TITLE>Search the site</TITLE></HEAD>
<BODY BGCOLOR=white>
</A>
The <A NAME=banner> tag opens the function, and a matching
</A> close tag ends it; in between are the function's
statements. Optional parameters would be specified after the
NAME attribute.
For full details on
script functions and parameters, see function declarations,
here.
All text in a script, whether Vortex commands or HTML, must be
contained within script functions. The exceptions are comments
(delimited by <! and >, e.g. <!-- comment -> or
<!DOCTYPE>
) and Vortex
directives such as DB and EXPORT.
