So... what exactly is "the bar"? There seems to be some disagreement. And that's natural since, being technology developers, we make up our nomenclature as we go along, so variations in nuances (nuancai?) can easily arise...



To some, "the bar" is the 2G line...

I think that "above the bar" means >2G. It is true that the bar was once described as having a thickness of 2G as IARV64 would not create a memory object in that area. I think that is now obsolete.

z/OS hurls if the PSW instruction address is above the bar. [[[... That would be any address >=2G, so I guess John holds to the 2G line view. -dbc]]]

Regardless of other restrictions that IBM may add to the use of storage above the bar, "the bar" is still the virtual address 2GB.




And to many, "the bar" is the very thick 2G to 4G area...

Isn't the reason it is called a Bar is because it is 2 GB in size and not a simple 1 byte from 16 MB to 16+1 MB? [[[... I think that reasin it's called a "bar" is simply becuase it is a word that is different from "line" -dbc]]]

Since the bar is 2G thick (or it used to be before Java started to use it), maybe it can be called "in the bar".

Since bars unlike lines do have some thickness I like to think of the bar being the range from 2G - 4G but that's just me. [[[... No, apparently it's not just you. -dbc]]]

Java uses memory "in the bar"? An IBMer stated that is impossible. [[[... It used to be impossible -dbc]]]

I vote for "within the bar".

I've never had a problem considering it "within the bar". I always thought of the "bar" as being 2G thick as opposed to the 2 dimensional "line".

And some have followed their own road altogether... [;)]

but possibly below the 4G quasi-bar,
or even up to the 32G neo-bar.

[[[... Well actually Bill goes on to state that he believes "the bar" is the 2G line. But I do like his creativity here. [;)] -dbc]]]




And to still others, "the bar" is the 4G line. That's my own view, and the view of ...

Oh-oh! Apparently no others? Woh!

Am I really going to have to change my whole world view here?
Or could I stick to my guns and bring all you other misguided souls around to my self-evidently correct view? [Sorta like the Casey Anthony jury, right?]

Are there any supporters out there of the >4G view?

Just wondering...
