[Chicago-talk] concurrent processes?

[Richard Reina]

Shawn thanks for your reply. It looks promising but the program crashes with:

Statement unlikely to be reached at test_exec.pl line 5.
	(Maybe you meant system() when you said exec()?)

Do I need some added syntax to use exec?

Is there a way to make the program wait until the terminal session has been terminated so that the value of $co can be obtained?
