You probably don't want to do it the way you're doing it now.

  a = "abcdef"
  a.sub(/cd/, "xy") # non-destructive, returns a new string

But to your question, =~ works quite well for "pos", as does #index:

  a =~ /cd/ # returns 2
  a.index("cd")

There's a *lot* more to strings and regexen than Pascal ever dreamed.
