In this article, the notion of BL-function on a nonempty set P will be
studied and for an arbitrary BL-algebra L and the element l ∈ L, the
notions of l-functions and l-subsets will be introduced. Moreover, using
these notations, the BL-code CL introduce and some related properties
and examples will be provided. Finally, I show that the structure of a
BL-algebra and the correspondence BL-code are the same.
