A combinatorial forcing for coding the universe by a real when there are no sharps

Logic 2009-09-25 v1

Abstract

Assuming 0# does not exist, we present a combinatorial approach to Jensen's method of coding by a real. The forcing uses combinatorial consequences of fine structure (including the Covering Lemma, in various guises), but makes no direct appeal to fine structure itself.
