Subject: Inserting a counter into a .each loop

I've got a loop that iterates through a string like so:

string.each_byte do |f|

  ...do something with f.chr

end

I would like to use a counter variable in this loop. I know I can add
'.with_index' but I need more control than that. I need a counter
variable in
this loop with state I can set when some condition is met and that will
persist through each iteration.
Does anyone know if this is possible? Thank you.
