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];
