<snip> Padegs says that "none of our operating systems were [sic] programmed to turn in the [ASCII] bit".
So, no-one was able to use the ASCII facility. </snip> These two statements are not fully the same. The former covers that none of the operating systems provided a mechanism for a problem state program to get the ASCII bit turned on. A program with sufficient authorization could have set the bit via LPSW. That doesn't mean that doing so was considered "supported" by the OS. There are many things in the architecture that a given OS might choose not to support.
