From this thread.

I noticed there and there the usage of "@@" in comments.

I know that "@ it is seen as comment in userRPL until end of line or the next @" but I did not try around the "@@" , is it 'just' persistent (that is, it can be seen on the calculator even after saving the program) or does it also expand on the next line until a closing "@@" is written? (that is, a multiline comment)

(bonus question: I do not remember seeing @@ in the official documentation for the 50g, is it another of my mistakes? )
I think you are now falling to two similar, but not identical language trap! That thread is pure newRPL discussion. NewRPL allows persistent comments with that format, while userRPL do not.

UserRPL is memory optimised in that regard, it cuts the comments out to preserve precious 128kB 2kB of memory(..or what the size were back in the first models using RPL).
