String replacement with grouping

If I wanted to perform a search and replace on a string where I need
to use grouping functionality, what is the best approach? There
doesn't seem to be any information available on how to do this. For
instance, given a string with a mix of lowercase characters and other
symbols, I'd like to convert this to string where the lowercase alpha
characters have been replaced with uppercase alpha characters. Since
Pattern and Match from Java are not allowed, what would be the best
approach? Thanks for any help.
