Yes. Barthes discerns between texte lisibles (readable) and texte scriptible (writable). Which was one of the inspirations to switch our focus from readablity to writability and create Writer. In Barthes' theory things are a little bit different, though ("readable" and "writable" indicate different kinds of written texts, not text in and post creation).

His distinction is maybe analogous to binary (readable) and source+makefile (writable).

Minor point: "text" here covers all sorts of artistic creations (TV, music, fine art), not just the written word.
