Start process within other's environment

Hi Folks, I write a little tool that execute two scripts automatically. The modification of the scripts are not allowed. The first script set some environment variables that are used by the second script. The problem is that I create and execute different processes to run those. How can I start the second process in same environment as the first, or is there any possibility to “export” the environment of the first process and “import” into another? Regards, Norbert
