from one perl code to the other

Whilst editing or during runtime? What have you tried, do you have any specifics about your problem? Please read I know what I mean. Why don't you?

Reason for this advice: there are many ways, depending on context, which you don't provide.

You can pass variables in voking one perl process from within another; you can share variables between multiple files or between packages running one instance of perl; you can use Sockets etc. pp.

What exactly is your problem? What are you trying to do (yeah, passing variables from one code...), but ... what code?

Do you even have any? Post it.
