If you mean the size of an array, you get the index of the last element by 
accessing the array in scalar context with an '#' just in front of the name.

Of course since Perl starts loading an array at elmt 0 you'd want to add 
one to get the size.

Here's the input and result from a run I just did on a server:

perl -e '
@a=(1,2,3,4,5);
print "size a eq $#a";
'
==>>  size a eq 4
