Lowercase to Uppercase and Uppercase to Lowercase

[Matix02]

Thank you everyone for your help. I got more than I thought.

So for 'always best performance' i take it we'll add an Array size on the U8 connected to a case with 1 parallell option and one normal, or will it be as fast if you use a parallell loop with N=1?

It probably won't be that easy to find a globally optimized solution that has the correct crossover point under all conditions. CPU architecture (cache sizes, number of cores, etc.) probably makes a difference. I would go with a plain loop because strings are typically short and that extra decision might even slow things down. 😄

Just thought I would give it a try.

You don't need the AND and the second Select function. If its input is TRUE, it means neither the To Uppercase nor the To Lowercase changed anything, which implies the bottom element is the same as the top element. It also means you don't need the lower Equal? check.

Yep, you are right.  Nice job!

Hello! Could you tell me what the name of the function is? Where can I find it?
