8.  Write the single Perl statement that will cause the change in

     "aeiou" have been converted to uppercase "AEIOU".

     $data = "aaaabcdeeeeeefghiiiijklmnoooopqrstuuuuvwxyz";
    
     MYSTERY PERL STATEMENT WOULD GO HERE.

     print $data;  OUTPUT IS:  AAAAbcdEEEEEEfghIIIIjklmnOOOOpqrstUUUUvwxyz

11.  Assume that you have called the localtime(time) function and
     that array @colors has values as follows:

     @colors = qw(YELLOW GREEN BLUE ORANGE GRAY PINK PURPLE);

     ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$dst) = localtime(time);  

     What one statement would be used to store in the variable $BGColor
     the appropriate color for the day of the week, where we want
     Sunday to always be YELLOW, Monday to always be GREEN, etc.?





12.  Write the one statement that would be used to open a file for
     input in your PERL program with the file handle FILEHANDLE.

     Assume that the file is named eleven.txt and that it is
     stored inside of your web folder.  It is NOT inside cgi-bin.

     The cgi-bin folder is where this script is being executed from,
     of course.  File to be opened:  "eleven.txt" is the name.
