Re^2: Global symbol requires explicit package name

but I thought I have already declared @state? I declared it as a shared variable... if I declare it again in the subs, I won't be using the same shared variable "state" anymore, right?
I'm a little bit confused... I know if I comment out "strict" it will work... but where else do you suggest I declare state?
Thank you very much

No you did not declare `@state`. You declared `$state` which is an entirely different variable. Most probably `make_shared_array()` returns an array reference to you. Check the documentation. And BTW, dont call it as `&make_shared_array()`: that is very "old" style and it has side-effects you probably do not know about. Deleting `use strict` is not a good idea. It pointed an error out to you. Removing `use strict` does not make the error go away, only the error message, the error being that `@state` is not the shared variable you think it is, a very fundamental error. Update: A rather handy trick you can try is using Data::Dumper to inspect your arrays and hashes. Then you do not have to write all these `for` loops with nothing but a `print` inside.

You declared `$state`. If it contains an array reference, you have to dereference it. Improve your skills with Modern Perl: the free book.	[reply] [d/l]
