Perl: export variable to shell

Hi,
I am running a series of scripts and I need to transport a particular variable across many scripts. I thougt of defining an environmental variable which I could access through. But I found that the variable dies as soon as the script ends..

Currently I write this variable to a temporary file and access from the other scripts.

Is there any other easier solution?

Thanks

I assume one script calls the other ones and needs to pass the variable on? See this link:

What shell are you using?

They are different processes..
It may or may not call the other and there is no order..

I am running Perl5 under cshell.

Thanks
