How do I call Tcl code from perl/Tk?

Assuming that you have a pressing need to call Tcl from perl/Tk then one "official way" to so would be via the ->send() and the ->Receive() methods. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
