Subject: Hints on the movie nested list control break...

Here are some hints that will perhaps help you for the control
    break processing, i.e. the change in movie name from Big to
    Casablanca or from Wizard of Oz to Young Frankenstein.

All you have to do is look at the HTML, to see what all needs
to be done when there is a CONTROL BREAK, i.e. a change in movie
name from the $lastMovie.

For your convenience, I have copied and pasted a few lines
of HTML which you can see and probably already have been looking
at with View menu Source from the
                http://student.cns.uni.edu/~venkman/moviesAtoZ.html
   URL linked to from
           http://www.cns.uni.edu/~jacobson/088/lastAssign2002.html

Please also take advantage of class37.html, the Thursday summary!
---------------------------------------------------------------------
   Control break processing - when $movieName ne $lastMovie is TRUE
---------------------------------------------------------------------

For the first movie, there is no previous movie.  That is the
purpose of the statement:

$lastMovie = " This will NEVER be the name of a movie, will it! :-) ";

in the sub makeNestedOLtags at class37.html page.
       --------------------

    Adventures of Baron Munchausen will be $movieName

    and if ($movieName ne $lastMovie) will be TRUE...

0. NOTHING to do, null string is all that is needed, as there
   is no </OL> needed for quotes, and no </UL> needed for previous
   actor, actress, category list closing. 

1.<LI> <B>Adventures of Baron Munchausen</B>
2.   <UL>
3.      <LI> John Neville
        <LI> Uma Thurman
        <LI> Comedy
4.      <OL TYPE=i> <B><FONT COLOR=BLUE>
           <LI>"I'm back! I got lips again and I'm gonna use 'em, baby!"
           <LI>"Your reality, sir, is lies and balderdash and I'm delighted
               to say that I have no grasp of it whatsoever."
           <LI>Escaping! We can't start escaping now! What would future
               generations think of us!?
           <LI>He won't get far on hot air and fantasy.
        </OL> </FONT></B>
     </UL><P>

The other case, when we reach the 2nd movie group in the file,
or the 3rd or 4th or 34th movie group of quotes, will be
as follows:     (see way below here for Big and Casablanca HTML)
                                        ---     ----------

When there is a change in the name of the movie, from the previous
  movie we have been working on, it is just like a control break
  from your COBOL class (control break processing).

    0.      </OL> </FONT></B>
         </UL><P>

    1.<LI> <B>Casablanca</B>
    2.   <UL>
    3.      <LI> Humprey Bogart
            <LI> Drama
    4.      <OL TYPE=i> <B><FONT COLOR=BLUE>

0. You need to close out the previous i. ii. iii. list with a
   </OL> and the previous bullet or UL list with a </UL>.
   Of course, there is no previous i. ii. iii. iv. list or
   UL bullets to close if this is the VERY FIRST MOVIE.

1. You need to print the <LI> for the current new movie name,
   the <LI> Casablanca would be printed.

2. You need to print the <UL> that starts a new list, when we have
   read Casablanca as the first record after Big.

3. You need to print the Humprey Bogart, but not the null string
   field because there was no actress in database, and then
   print the category Drama.   print $record[2] through $record[4]

4. You need to then print the <OL type=i> tag that starts
   the nested list for the quotes, all of the quotes for the
   film.  There is at least one quote, this record from the
   database, but probably several more, as they are encountered
   in sorted order.

All of the above action must take place inside of your
if statement.

When you are printing the 2nd or 3rd or 4th quote from a movie,
all of the above action is avoided.

When you print the 1st quote from a movie, the above action
happens, then AFTER the above action, the printing of the
quote happens.

  <LI> <B>Big</B>
     <UL>
        <LI> Tom Hanks
        <LI> Elizabeth Perkins
        <LI> Comedy
        <OL TYPE=i> <B><FONT COLOR=BLUE>
           <LI>"I'm your best friend. What's more important than that, huh?"
           <LI>Susan:  I want to spend the night with you.
               Josh: You mean like sleep over?
0.      </OL> </FONT></B>
     </UL><P>

1.<LI> <B>Casablanca</B>
2.   <UL>
3.      <LI> Humprey Bogart
        <LI> Drama
4.      <OL TYPE=i> <B><FONT COLOR=BLUE>
           <LI>We'll always have Paris.
        </OL> </FONT></B>
     </UL><P>

Good luck, 088 students...
