Vortex scripts reside in HTML-like text files on a Web server,
typically in the
/usr/local/morph3/texis/scripts (Unix) or
c:\morph3\texis\scripts (Windows) directory (see
The source files typically have a
and the object files have a
.vtx extension. Vortex scripts are
run by the CGI program
texis upon request of a Web browser (or
command line). The program will automatically re-compile scripts
whose objects are out of date with respect to their source, so no
explicit re-compiling by the user is needed.
A Vortex script is delimited in an HTML file by
... Vortex directives (if any) ...
... Vortex functions ...
... other HTML (ignored) ...
There can be multiple
<SCRIPT> elements in a file; they
are concatenated as one Vortex script (though functions cannot be
split across script blocks). All text outside of
<SCRIPT language=vortex> tags is ignored.
The syntax of Vortex scripts, with few exceptions, follows that of HTML. This allows the easy intermixing of the two, and minimizes errors if a Web browser ever views a Vortex source file or script. All Vortex commands and directives are HTML tags, some with optional attributes. Like HTML, attribute values may contain whitespace and other non-alphanumeric characters if the value is enclosed in single or double quotes. Tags and attributes are case-insensitive; however function and variable names are case-sensitive.
The following is a minimal example script that just prints "Hello, world!":
