It isn't impossible to modify the existing form, but I'd
begin with a whole new form and fill it with the fields from
the file. Basically, the "value" of each field would have to
be set to the text extracted from the file.

If you are using the same program to edit that you used
to create the file and if that script does not use a field
called "edit_file", you could use this URL:
/cgi-perl/editform.cgi?edit_file=myfile.txt
You can retrieve the parameter using this:
use CGI;
my $q = CGI->new();
my $file = $q->param( 'edit_file' );
You will probably need to add some path information to
$file. (The example above uses the object-oriented
interface to CGI.pm.)
: Here is a sample of a text file it creates: The data entry
: form program outputs the field names that label the data
: in the program and in the text file.
:
: <DATE_FILED>Wed Mar 17 15:29:01 2004</DATE_FIELD>
Is it supposed to be <DATE_FILED> and </DATE_FILED> or
<DATE_FIELD> and </DATE_FIELD>. You could use like it is
above, but it would be better if the opening tag matched the
closing tag.

You need to read up on regular expressions and on
parsing files. This is a poor format. Writing the file in an
XML format would allow you to use an XML parser module to
extract the information and might allow easier information
sharing down the line. An RDF schema would probably be
useful here.
I think the example in the book was meant to illustrate
how files and forms are processed. This is not an excellent
starting place for a full featured story editor.
