Need Help??

You' re right.

I was wrong just because I think that Tie should manage also inner hash. Now it's all more clear and I fix my program so it now works as expected.

Thanks to everyone.

sub ab { $hash = { abc => 'cde', }; return "$hash is the value"; } $str = ab(); with $str how can i access the has of abc and its value. Since, its hash ref in a string..	[reply]

Basically, you can't. The memory allocated to `$hash` is released as soon as `ab` returns because there is no reference to `$hash` anymore. If you need a reference to data, keep it as a reference. Don't convert it to a string.	[reply] [d/l] [select]
