Subject: New link to myCGI.lib and testLib.cgi review

Hi 088 students,

   The new link from our class web page at ~jacobson/c088.html
shows the application and the library file code myCGI.lib and
the Perl script code for testLib.cgi.

   I have added several new features to it that we did not
do in lab.  Note especially the myLib.cgi heading function that allows
you to say:                               -------

   print heading("UNI Panthers"),

         heading(2, "RAGBRAI rides again next week"),

         heading(4, "22 years ago today, Nicaraguan revolution"),

         heading(5, "PERL rules");

   Output of the above:

   <H1>UNI Panthers</H1>

   <H2>RAGBRAI rides again next week</H2>

   <H4>22 years ago today, Nicaraguan revolution</H4>

   <H5>PERL rules</H5>

  The guestBook.lib and testLib.cgi and myCGI.lib files will
all be discussed tommorrow.  I have prepared a handout of the
myCGI.lib and testLib.cgi files, along with the guestBook.lib file.

  The only other thing we did today was the sleep function,
where we
         sleep 1; to pause 1 second
      or sleep 5; to pause for 5 seconds.....

  We did this in the context of nested loops:

  for ($i = 1; $i <= 12; $i++)
  {
     $stars = "";
     for ($jj = 1; $jj <= $i; $jj++)
     {
        $stars = $stars . "*";
     }
     if ($i < 10) {
        print " ";
     }
     print "$i: $stars \n";
     sleep 1;
  }
  print "That's all for now! \n\n";
  sleep 5;
  print "Bye bye! \n\n";

  See you on Friday in class.  Friday should be a good review for the
Monday exam, but there will be alot of new stuff mixed in with the old
concepts too.

  Mark
