Rex, what do you mean by “not discovered”? These data types (apireq (api request), exclamation, cmd, iterator, backreference) exist, but there are no direct commands for working with them? That is, these are “internal” data types available only to the system itself?

Someone ( :grinning_cat_with_smiling_eyes: ) has already discovered them, otherwise how could I make the list???

When you find out how to use them, let me know :wink:

Once I had found a way to generate “exclamation”, but for my stupidity I didn’t write it down and now I don’t remember…
