Unity Pro - Easy to copy/paste?

I have a series of small subroutines where each tag is eassentially the same except a number like A100, A101 will be A200 and A201.

Is there an easy way to copy and paste and change?

Their search/replace is not very good. Ideally I'd like something like RSLogix 500 where you see the tags you are adding and change them neatly in a table right before you paste the code.

Right now I think I have to use brute force method which is long and tedious.

Why not use dfb instead of subroutines. Define a function block with inputs, then attach to the number you are wanting to change to that input. Then use that input within the dfb.

If you really must use a subbroutine - you can export the subroutine to a text file, edit the file then import

Awesome!

Thanks for saving me a ton of time!

Exporting a subroutine in LD can only be saved as an XLD file. It is not easy to work with though.

Defining a function block is the way I will go.
