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.

There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James My blog: Imperial Deltronics
