Dave,

The reason for this is really pretty simple.

"Internal" page numbers (those which DBT generates, such as braille page
numbers in a braille document) must always be strictly numeric in form.  You
can switch between Arabic and Roman notation, but the page number is always
Roman.  So the page number is regarded as a part of the dollar code.  It
just sets a value which is used to generate text and is incremented from
page to page.

"External" page number (print reference page numbers) are regarded as words.
Largely, this is because they must be translated just like any text.  DBT
doen't "parse" and "rewrite" them the way it does "internal" page numbers.
It just transcribes them and puts them in the document.  The [lea] code is
in fact nothing more than a variation on the [tab] code.

Hello everyone:

It has always baffled me as to why the values that are typed for the [lea]
(Print Reference Page Number) and the [pv] (Set Braille Page
Number) codes are entered differently from one another.

When you use the [lea] (Print Reference Page Number) code, the number value
for this code is entered as text, outside the [lea] code, e.g.
[lea]1

Whereas, When you use the [pv] (Set Braille Page Number) code, the number
value for this code is entered as text, inside the [pv] code, e.g. [pv1]

It would be nice if the values for the [lea] and [pv codes were entered in
the same way, that is, entering the number value inside the [lea] code,
instead of outside the [lea] code, as it is at present.
What do other users think?

Sincerely:

Dave Durber
