Sorry to ruin your Xmas break Mathias!
Originally I wanted to call an existing rename profile (in the same way as a filter) with a MScript. Couldn't see how to do that. Filters have an ID to call but I have not found ID tags in the rename dialog & didn't dig deeper.
Not all files contain all the same items I want to change. Some have one character to change, others some or all.
I wasn't sure I could apply a single @var to this task. I expected conflicts.
I concluded that with multiple possible case-sensitive rename actions, I needed to queue them discretely, so gave them different @vars.
Would a Function concatenate multiple changes...?
As you know I like to cause headaches with MultiScript - I find it therapeutic.
