Baabnq does not have commenting conventions, except for Routine Signatures. Routine Signatures are entirely optional and are comprised of two parts: The Type Signature and the Implementation Signature.
The Type Signature dictates how and with which types a routine is to be called. See Call Conventions.
The Type Implementation describes and illustrates the functioning of a routine. It usually consists of a textual description or a parallel implementation in a language like Haskell or Uiua.
