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

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 (Help).
