I tend to agree, which is why I wanted to clarify what he had in mind. I know how to turn the bit off without application awareness, and having the bit off will have implications on other aspects of the display (as you point out). I could restrict the bit change to monochrome displays only, but again it's hard to say if that's what he had in mind.

Bruce,
Yes, assuming that what you're after is changing attribute bytes of
x'3x' to
x'2x' on the fly.
I doubt that is what he is really after. I think he wants to achieve the
alternate colors available using x'3x' but without the visual artifacts
of
the column separators. And the 5250 data stream has no way of doing that --
it is under the control of the 5250 emulator or display device in use. As
James points out, you can configure that on some Infowindow models and
certain emulators. But by definition the x'3x' range of attributes
have the
column separator bit set and to my knowledge, there is no data stream order
to tell a device to turn off its method of displaying column separators. As
James also points out, how column separators are implemented also varies,
with some more ugly than others.
Maybe I just misinterpreted what James wants, and he is OK with mapping back
to the colors in the x'2x' set of attributes.
