After Googling this stuff, we found this table named 'Graphic Escape
APL/TN, Code Page 310' and here is it's picture:

Bullseye, this picture is identical to the screen output of the little ILE
RPG program we posted here running on IBM iSeries Access for Windows 5250
display emulation (except it reverses the row/column axes).
We stumbled on this hidden font in iSeries Access because we wanted to
create on AS/400 a horizontal scroll bar with words in the shaft, sort a
like a volume fader, where the user can mouse-drag the scroller
left-or-right and drop it onto a word, for example:
<======SOFT=====MEDIUM====LOUD=====SPINAL TAP======>
But we observed that, although writing a scroll bar then overlaying the
scroll bar shaft with words DISPLAYS fine, it BEHAVES poorly: the instant
the user touches the mouse onto the scroll bar, all the word disappear,
leaving a broken dashed "railroad track" remaining, instead of solid line
"railroad track."
And then we wondered if enveloping the words under a transparent data order
would make the words stick to the railroad tracks when the mouse moves.
It doesn't.
Insane?
