As I already wrote, I'm just a bloody beginner. Wasn't aware of max nor
-rot (maybe as a matter of ignorance).

That looks to me a bit as coming from mainframe programming.

Regarding the pure value of comments, I had to admit that I learned it
the hard way. IMO, however one likes it, at least sometimes comments
make the life much easier, even when modifying/extending your own code
the year after... can't imagine that it's different in Forth.

Of course, comments have to be both correct and meaningful.
