;) $a is an anonymous reference to the array defined @$a resolves that reference [EMAIL PROTECTED] prints out the index of the last element of array $a->[elemmentnumber] is used to access an element thru an array reference. so $a->[EMAIL PROTECTED] simply gives you the last element of the array
an easier method(if you think so) might be perl -e '$a=[1,2,3,4,76]; print $a->[EMAIL PROTECTED]' -----Original Message----- From: Marcos Rebelo [mailto:[EMAIL PROTECTED] Sent: Thursday, March 10, 2005 8:23 PM To: Perl Beginners Subject: Simplify perl -e '$a = [1,2,3,4,7]; print $a->[EMAIL PROTECTED]' This is correctly printing '7' but '$a->[EMAIL PROTECTED]' seems to be encripted code.
