Hi gmayor

Thank you for replying. AI still needs a lot to deserve even the "I" in it.

As I mentioned in my post, ([0-9]) and $1abc are only examples. What I actually need cannot be easily covered by wildcards.

To simplify things, let's say that I want, with regex, to replace b([13579]*)c([13579]*)cd with b$1c$2c46d in instances that I choose.

I can use the macro here, but this requires creating hundreds of strings! That's why I need to use regex.
