regular expression and grep function questionsby dicty (Sexton)

dicty has asked for the
wisdom of the Perl Monks concerning the following question:
What does "\z" mean in Perl?
I have a question about grep function. For the code below:
my @new_array = grep(/^\s+\d+\s+/, @array, $number);
What's the variable "$number" for? I remember grep only takes two input variables, one is the expression and the other one is an array.
