[UEB Maths] UEB special modes

[Janet Reynolds]

I think I really need to get us back on track here. We can't afford to
be too creative at this stage, we need to keep focussed on the grade 1
indicators and the representation of functions. As part of the
consultation in New Zealand I am getting feedback from Maths users about
the grade 1 indicators, so will send a longer message later today or
tomorrow. Stephen, I don't think you mentioned the teleconference in
your reply. How available are you in those two weeks in July? I will
give Bruce a ring.

If we were at some stage interested in introducing a compressed mode, an
alternative to the one outlined by Joe which focuses on the arithmetical
signs and brackets, would be one which instead has a compact form for
subscript numbers (especially useful for chemistry, but also for maths).
I'm sure we must have mentioned this before in Committee 2 (and rejected
it), but perhaps only within the context of normal UEB - I've certainly
thought it.

You just use lower letters to represent subscript numbers within this
mode, e.g. x sub 1 is just x dot 2, and x sub 1 y sub 2 is x dot 2 y
dots 23. But for this we would have to switch the superscript and
subscript indicators from lower e and lower i. An available sign to
switch the subscript sign to is the recently discussed dots 16 (which by
chance is the current BAUK subscript sign), and is "similar" to lower e.
It would be nice to similarly switch the superscript sign to dots 34,
but this is assigned in UEB as the simple numeric fraction line. The
traditional superscript sign for BAUK (and elsewhere) is the again
recently discussed dots 346, but in UEB we have it as the radical close
sign. (Can this easily be altered?)

Although I am not necessarily proposing this (unless others showed
interest), I thought it would be best to flag it now before it is too
late. If we want to keep lower letters available as a series for future
use in a special mode, we should consider changing the current UEB
assignments for superscript and subscript signs; certainly dots 16 and
possibly dots 346 spring to my mind.

I note also that lower g, currently the prime sign in UEB, would also
best be reassigned, as the prime sign would be used in these same
technical contexts.

Of course, it is not my intention here to open up old discussions.
