No, the patch levels aren't directly shown.  It's the base level designation.  If that term is not familiar: base level is a DEC (and others) term for a step in the development cycle where a bunch of stuff gets integrated.  Typically there were a dozen or so base levels per release.  In early RSTS releases, the minor version was a letter and the base level a number (V4A-12); then as of V7.0 the minor release code changed to a letter and then the baselevel became a letter to have the whole thing fit in 6 characters.
