James,
Thank you for the insight on the current activities at ICEB!
On the topic of this thread -- if I understand correctly, the proposal
under consideration by ICEB would add the visible/blank space (dots 346)
and underscore/lowline (dots 46, 36) to the list of symbols that can occur
within numeric mode without breaking numeric mode.
The list of non-numeric symbols permitted in numeric mode appears in UEB
6.2.1. If the proposed changes are adopted, the visible/blank space and
underscore/lowline would have to be added there.
Additionally, if the proposed changes are adopted by ICEB it would also
require updates to GTM 3.6.
Best,
_don

Hello John and all,
You raise a very interesting question about missing digits. This is, in
fact, as George suggested, something that ICEB are currently looking at.
The discussions are at an advanced stage and I am hopeful a conclusion
should be close.
The current "correct" method would be to use an appropriate indicator for
the blank, (dot 346 for a visible space, or dots 46-36 for an underscore,
etc), followed by numeric indicator and the digits, i.e.:
with visible space: +#bj
With underscore: .-#bj
John correctly states that neither the visible space nor underscore can
occur within numeric mode, so you always have to repeat the numeric
indicator for further digits. So consider 2 blank 0. This becomes:
With visible space: #b+#j
With underscore: #b.-#j
Notice that with the blank after the first digit, the braille is one cell
longer.
Clearly this is not ideal.
The current proposal with ICEB is to allow the visible space as part of a
number, particularly for younger learners, where such arithmetic sums with
omissions are most common. This would make our two examples become:
blank 2 0: #+bj
2 blank 0: #b+j
Now both cases are the same length and any columnar arithmetic sum would
also still be correctly aligned.
The proposal with ICEB also suggests substitution of the visible space for
a blank, again for younger learners.
As I said, this is still, a suggestion, so the current "correct" method
should currently be used.
Incidentally, if you aren't already, you might like to subscribe to the
ICEB-Announce email list: it is a one-way announcement-only list where you
will hear of updates to the rules and announcements to the forthcoming ICEB
General Assembly which will be in London in May 2020.
You can find details on www.iceb.org/icontact.htm
I trust this helps.
With best regards,
James.

Subject: [ueb-ed] Missing numbers which appear at the start of a part
given number
Hi,
Colleague is working with sums and ‘number cards’.
One of the missing numbers is part of a number, i.e, underscore followed
by the digits 2 and 0.
What is the correct format for this, is it dots 346 followed by number
sign and the 2 and 0? Use of the number sign indicates a number follows in
UEB so it can’t come before the ‘ing’ – and should it be spaced or next to
number sign followed by the two digits?
Thanks.
John.
J Blake
