I discovered that a rpl variable can include points, that is neat, I thought only alphanumeric symbols were allowed.

Surely I miss the definition of what a rpl variable can contain, does someone remembers where I can find a reliable definition? I will try to search in the 50 user guide and Aur asap.

Side question: for rpl programming and built in functions in the 50g, could be that also the documentation for the family 48 and 49 (aside from the 49 g+) is useful?

Both questions are still open, although due to some searches on the forum I realized that it is likely that whatever book about userRPL, aside from the focus on functions that may have changes, is helpful. So I should not restrict myself to the AUR only.

But still I would like to find a definition of what can be in the variable name in userRPL, did not find it so far.
