Hi, James:
Hello again. Please keep your replies on the list so we can all learn from and help each other.
Thank you very much! Now, I am clear about the question.
Do you mean the outmost parenthesis captures the value assigned to variable? Then the contents between /......./ are matching regular expression?
Yes, the /.../ part of the line you posted was a regular expression match. Whatever was in Perl's default variable $_ was searched for the expression. Everything matched inside parenthesis was captured and two of those values were assigned to $t and $i.
