No, exec will always cause your script to exit.  Try using "perl -w", you
will probably get a warning like this:

	Statement unlikely to be reached at foo.pl line 345.
	(Maybe you meant system() when you said exec()?)   


See "perldoc -f exec" or "perldoc -q exec"

=head2 How come exec() doesn't return?

Because that's what it does: it replaces your currently running
program with a different one.  If you want to keep going (as is
probably the case if you're asking this question) use system()
instead.
