Hi all, I see some codes as following
my $regexp= "(([gatc]{3})\\2{3,})"; my $string=~/$regexp/; What is the meaning of {3,} of in \2{3,} ? I know \2 is a backreference here but not sure {3,}. I check the camel book and some perldoc but I can't find answer. Thanks, Li __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
