Sorry, but I think the above comment is perpetuating the confusion.


The BlackBox documentation does not refer to ASCII files. In these files
0A (LF) may, depending on the
operating system and program, be ignored, be an end-of-line marker, or
be part of an
end-of-line marker.

In BlackBox Texts the BB documentation applies, and states that 0A is
never used.

In, for example, a Controllers.EditMsg, used by Views.HandleCtrlMsg, a
View can react to any character
in any way it likes. The BB documentation states a convention for
character OA, and Chris has given an example of
its use.


Cheers

Robert
