Yea, when John wrote that, it made sense, just looks strange.
Unary plus is indeed strange in most everyday contexts, especially in
business logic. In a language like RPG, the most compelling rationale
for even having it in the language is for symmetry with the unary
minus. (If you're thinking that sounds pretty weak, I agree!)
In other languages, unary plus is not *as* useless, though still not
particularly useful. You have to be doing something fairly exotic for
it to actually be important.
