The idea prompted more by the quick fire variety of topics than the range of 
any one particular topic.

Programmed Symbols, Translation Table, etc.) are needed?

This trick has nothing whatsoever at all to do with the content of mode tables 
or any alteration of the "standard environment". This is purely a matter of 
support for characters in the 3270 data stream implementation. Casting my 
mind back, I think the old 3279 may have imagined it was rendering a solid 
circle but it ended up the shape that requires skill to execute a "drop kick".

On some 3270 implementations where I ran my little transaction the rendering 
was just a hopeless squiggle. In all of them the effect was maintained that 
your eye was drawn to the blinking shape - whatever it was - while you could 
very easily read the static text.

You just need to put X'3F' into your data stream and make sure no busy-body 
programming which thinks it knows better does anything to mess with it.

It may well be easiest to try it out with the BUFFER operand of an 
Unformatted System Services (the true USS) message. VTAM takes a possibly 
undesirable interest in the content of a message set up with the TEXT 
operand but has a completely "hands-off" approach to a message set up with 
the BUFFER operand.

Note that, apart from USS message 10 (and 0, and 11, checking the book[1] - 
and 13) - USS messages are error messages and so deserve to contain 
arresting highlights.

[1] According to the Communications Server SNA Messages manual, USS 
stands for Unformatted *Session* Services - ho hum!
