in reply to 2d arrays in Perl?

If you want CourseCodes to be an array, you can add elements to it like this: 
push @{$thePupils[23]{"CourseCodes"}}, "99-A";
push @{$thePupils[23]{"CourseCodes"}}, "99-B";

and then access them like this: 
print ${$thePupils[23]{"CourseCodes"}}[0];
print ${$thePupils[23]{"CourseCodes"}}[1];

    Instead of this.. 
    print ${$thePupils[23]{"CourseCodes"}}[0];
print ${$thePupils[23]{"CourseCodes"}}[1];

    Why not just do... 
    print $thePupils[23]{"CourseCodes"}[0];
print $thePupils[23]{"CourseCodes"}[1];
