I've seen some places where the ^ROUTINE global is fully or partially deleted after compilation. I suspect that the same would work for ^rMAC or ^oddDEF - you'd have to test it. One company that I'm aware of encrypts the ^ROUTINE global after compilation which has the added "benefit" of making it extra difficult to debug errors! If you really want to hide your code you could compile the code on an identical system and then just deploy the object code.

I had the same thoughts but decided to make assumptions that allowed me to code using the least characters. If you cater for the tricky stuff you'd probably have to double the length of your code.

Shaved off another character
