Dan, It appears the $apple->[2] and $apple[2] are not the same thing.
#!/usr/bin/perl -w use strict; my $apple = [4,5,6]; #example of a scalar representing an array print ref($apple) . $apple->[2] . "\n"; print ref($apple) . $apple[2] . "\n"; errror msg: Global symbol "@apple" requires explicit package name at F:\perlex\Perl-1.pl line 7. Execution of F:\perlex\Perl-1.pl aborted due to compilation errors.
