BreakPoint
Rube Goldberg Code
In LV, regexes are implemented with an external library so there is some overhead versus an all-native implementation. We are talking about microseconds so unless you are unleashing this on a monster database you probably won't notice.
The regex in this case is pretty straightforward. (.) is a capturing group of a single character. What I do is grab two characters this way, and then the replacement is $2$1 which is second capture group followed by the first one (ie. a swap).
Yet another non-Type Cast and Non-regex version:
This reminds me that someday I will post an idea that all array functions treat strings automatically as the byte arrays they are, without the String To Byte array and reverse, this version would not look that bad. (I'd probably still Type Cast, but a fun game to play is how many different ways can you do the same operation).
Another job for Typecast Man! 😄
As Dennis correctly pointed out here, there are better ways to do the hex-string and string-hex conversion. I am only showing one of the two here, but you get the idea.
The toplevel program (hotplate.vi) is a mindboggling collection of rube constructs, greedy loops, useless loops, and datatype conflicts. The code coud be rewritten with 10% of the resources. A quick excerpt is how two controls are formatted into a instrument string. Most of the rest of the code is even worse!
See the original thread for more details.

I actually played with that idea a long time ago and came to the conclusion that there might be difficulties with e.g. arrays of strings. Currently, we cannot have arrays of arrays, so that might be similar, maybe ... maybe not? This requires some thoughts...
There are also some related ideas, for example to allow FOR loops to autoindex over characters of strings.
