Dear Nikki:

Computer Braille, sometimes called grade Zero, is a one-for-one
representation of the text in Braille.

It is like Grade One Braille but does not use the Composition
Signs for Capitals, Italics Letters or Numbers.

It represents numbers as lower letters with no number sign
preceding them, the same way Nemeth does, at least in the
T-Braille implementation of Computer Braille.

In the B. A. U. K. implementation of Computer Braille, numbers
are represented by letters with a dot 6 added.

These two implementations of Computer Braille are separate and
distinct from the Provisional Computer Braille Code as published
by B. A. N. A.

The Provisional Computer Braille Code has two-cell signs for
Grade Switch, Capitalization begin/end, Italics, Bold and
Highlighted in addition to a representation of the various
letters, numbers, punctuation and other symbols used in computer
work.

Hope this explains the matter.

Brian
