Key/value pairs are stored randomly in the hash's internal structure. This is done for efficient lookup. There is a way to keep hash keys in a certain order (see 'perldoc -q sorted'), but I wouldn't recommend it until you know what you are doing. What are the key/value pairs you wish to store in a hash? You only mention a sorted array. Are the array members to be used as keys or values in the hash? > Secondly, i want to delete the first occurence of key/value pair. First in what sense? Since hashes do not have an intrinsic order, the concept of 'first' is generally not meaningful. Perhaps you can tell us what exactly you are trying to do. It would also help including some sample code that you think will do what you want. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
