So I have a perl script that runs another script that someone else wrote. The 3rd party script imports data into a database. When it is done, it includes a "Press any key to continue..." line and waits for input. How can I have my perl script provide that input?

Right now I can calling this 3rd party script with a system() call. Also I am using ActivePerl and this 4rd party script is not written in Perl.
