There is a bug in the documentation.
Typol strings are implemented as prolog atoms.

So in Typol it is getsym("slen",F),
and in prolog it is getsym('slen',F).

(In this example you can also write getsym(slen,F) in prolog because the
first letter is in lowercase and there is no special character in this name)
