[Solved] How I can make bold formatted string?

[Vtile]

Hello, I found today while reverse-engineering some simple userRPL programs found on HPcalc.org that it is possible to make a BOLD text in atleast HP50g. It only works while inside a string object (between "" marks), and it is somesort of set (two separate characters each side of bold text, I assume somesort of start/end glyps) of special characters, but I can not found any reference to it other that this one LM317T program where it is used in two places.

What are those magical characters and how I can get access to them, in HPUserEdit 5 they are drawn as double exclamination marks.

Here is a snippet of it.

Code:

"       
BravoRPL
 ! ! " 1 DISP

I did found the right search words..

Where all this information have found, while HP documentation seems to be *censorship* on these. .. OK wait a bit, it there is something on HP50G User's Guide near page 870 or so, I'm sure that is on the CD that came with the calc... while I don't have had DVD-drive for many years. *fail*
