When I compile the following ILE RPG program and run it in my standard

see symbols like triangles, ovals, diamonds, inverted and sideways U's,
Greek letters alpha epsilon rho, tiny single byte combinations of the
letters HT, FF, CR, LF, HL, VT, Âplus-sign-over-minus-sign symbol,
infinity, the empty set, arrows, some little things that look to me like
picnic tables and christmas trees . . .

You've probably know this already, but if you run it on an old
InfoWindow, assuming you've still got one, and presumably on an
original 5250, you don't get the same effect. If you produce the
pretty display in iSeries Access then copy / paste the screen to
Notepad it resolves to this:

 à à à à à à à à $ . < ( + |

That is also what you get when you run the program on a genuine green
screen except that the final Å character appears blank.
