The full power of Perl is well outside the scope of this document. Looking
in the function list in the section
can give you some ideas. O'Reilly has some good Perl books. Enter
"perl" in the search box at

If you need help, you might search the listserv at
http://mail.lon-capa.org/mailman/swish.cgi or consider joining the
users listserv to ask other users for advice at
http://mail.loncapa.org , or use the Help link to
contact the Help desk. Often other users are quick to provide help.
Our advanced users often come to prefer the XML interface for the problems,
available through the EditXML buttons. Covering the XML format is
beyond the scope of this manual, but you can learn a lot by using the editor
to make changes and seeing what happens to the XML. Supported XML tags are
discussed in the Tags Used in XML Authoring section ().
