[nfbcs] Brailling computer code for embossing and display on a refreshable braille display

[Rasmussen, Lloyd]

It depends on how the user adjusts the settings of the notetaker or screen reader on which the braille is being read. I don't think there is much you can do.
Make sure that the proper computer braille line continuation indicators are being used for lines longer than 40 characters. This indicator is 4-5-6 1-2-3-4-6 in EBAE computer braille code (CBC) or dot 5 in UEB. The dot 5 is also used as a line continuation indicator in braille music.

Subject: [nfbcs] Brailling computer code for embossing and display on a refreshable braille display

Apologies in advance for what might be something I should already know.  I have searched for an answer online with a moderate level of diligence, but without success.
 
I am a sighted braille transcriber and I have a question about formatting when brailling content that is intended for embossing, but which may also be read on refreshable braille devices (RBD).  This question has come up in my embossing of a computer science textbook with programming code that should be displayed with specific line indenting and line breaks.
 
When brailled content is to be embossed on the usual 11" x 11.5" paper, it is formatted with a 40-cell line length.  If a BRF file is displayed by a RBD with 40-cell width, formatting would display as expected with hard line breaks and indenting retained from the original. However, if displayed by a RBD with less than a 40-cell width, I am not certain how line breaks and indenting will be displayed.

Does a RBD retain indenting and line breaks as would a programmer's editor like EMACS, or are wrap-around lines displayed starting at cell 1?
 
Is there a way to format a BRF file so all formatting of computer code is retained?
