Subject: search pattern

Hi all,

I have a Ruby script as follow. What I try to do is to find a pattern in
the string and report its position. I wonder how to get the position of
pattern in the string.

Thank you in advance,

Li



seq="5'aaaAAAAAACCCCCCCCTTTTTTTGGGGGGGGG-3'"

seq.upcase!# change to upper case
puts "old sequence:"
puts seq.gsub!(/[^A-Z]/,'')# extract the string
puts pattern if seq=~/AC/

#how to get the position of pattern in the string?
