Fellow student and complete beginner here.
In -11h, 11 means your data is a symbol and – means its an atom. A type num code of (positive) 11 would have meant a symbol list, here you have a symbol atom (one value). The h show that the value that you get back as the type’s numerical code is a long.
q)type ``zaphod
-11h
q)type ``zaphod``beeblebrox
11h
(I would rewatch the data type and cast videos if that remain unclear).
Happy hacking!
