Perl references are indeed similar to C pointers, in that a reference variable contains the "location" of another variable and allows one to indirectly access the value of that variable, but there are some differences. For example, one cannot do arithmetic on Perl references, e.g. incrementing a reference to iterate through an array. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
