I've never seen anywhere I would need a unary plus even when programming in C.

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.
