I'm by no means a strong Braille reader myself, but I still find Braille
very useful and try to read as much as I can on my Braille display.
I started learning Braille about 2 years ago.

Subject: Re: Your Experience with Braille Displays
Hi,
I'll add the following to this discussion. I'll preface my comments
by stating that I'm new to programming with my time in it measured in
months. I'm a little more seasoned at html though which I don't
consider a programming language although it has a few of the same
quirks.
I use Jaws 11 and a focus 80 braille display on a machine running
windows xp pro and another running windows xp media center. I simply
could not conceive of being able to code efficiently without one.
Proofreading is so much simpler with a braille display than with
speach alone. Also, editing the code can be much faster since a lot
of braille displays now adays have routing buttons right above the
cells that you can push to jump right to a bit of code you wish to
edit. For instance:
1 // c++ program to make your pc greet you personally.
2 #include <string>
3 #include <iostream>
4 using namespace std;
5 int main ()
6 {
7 string nombre;
8 cout < "What is your name?" << endl;
9 cin >> nombre;
10 cout << "Hello, " << "nombre!':
11 return 0
12 ]
This will not compile because I've got some syntax errors. On line 8,
I've only got one left angle bracket instead of two (< instead of
<<). On line 10, I've got a single quote (') and a colon (:) instead
of a double quote and a semicolon on the end ( " and ;). On line 11,
I don't have a semicolon at the end of my line and line 12 has a right
bracket instead of a right brace ( ] and not a }).
Now, when I run this code, my compiler throws a fit and gives all
sorts of annoying little error messages. When I go back into my code
to check it, unless I've got my punctuation settings at maximum with
speech and arrow down line by line and wait until the speech is over
for that line, I won't spot these errors right away. It might take me
a few passes to find them. This is only 12 lines of code. I can't
imagine how long and grueling this is with hundreds of lines of code.
With my handy dandy focus 80 brailel display, however, I pan down the
lines of code, run the old fingers across and spot the errors pretty
quicly. I hit the routing button above that lonely < sign on line 8
and type another one to make two. I do the same thing on line 10 at
the end there to get my " and ; onto the line and I slap a semicolon
on the end of line 11. I get to line 12, curse, delete the offending
bracket and replace it with a brace by first routing to it with the
routing button and just doing my replacement.
also, I'm able to perceive all the indentation in the code nicely.
I've got my braces at 8 spaces in and my text in the block at 5 spaces
in from the left margin. When I learn Pyton, I don't anticipate
having any trouble using braille. You CAN make Jaws tell you exactly
hwo many blank spaces there are before some text but it's pretty
annoying to hear.
In html braille is even more critical since you can have lines and
lines of text until you get to your tags. Having your screen reader
spell every word or give you each and every punctuation mark in a
multiparagraph webpage is simply too horrrible to think about
especially when, most of the time, you just forgot to place your end
tags just so or have two less than signs when you needed a less than
and a greater than.
You really need to get yourself a braille display. If you aren't a
strong braille reader yet, make it a priority to become one. It will
open up a whole new world for you and not just in programming.
Hope this helps.
Alex
