Maze digger program

I created a program that builds mazes. The mazes can be any size and are completely pseudo-random.

The program is very easy to use:
You place the turtle in the ground and run the program like this:

programname <width> <length>

You can get the code here: http://pastebin.com/a4Bxy9cQ
Please note I didn't prevent the turtle from messing up when it gets blocked by any mob or player, so keep those away from the turtle.

So what happens if I do

maze 1 100

And shouldn't it be

maze <width> <lenght>

Instead of

maze <width> <height>

If you do maze 1 100 it'll make one straight line, and you're right about the <length> thing thanks

Nice!
It seems you can easily add height 1-3 as third argument and blocking protection (attack once a second if unable to move).

This is cool but it seams to make a maze twice the size I ask for.
I can't fault the results thought this looks very nice next to my house.

when i ran this program, this was the resulting 'maze'. any help?
it was running well but then received this error,

0bios:40: vm error: java.lang.ArrayIndexOutOfBoundsExeption: 256

I'm thinking that means that there was a problem with the lua implementation in the version of ComputerCraft you're running. Or maybe just the instance.

The reason that it gives mazes that are twice the dimensions asked for is because it moves two blocks for each "turn". This gives a nice 1 block wall around each passageway, but it also doubles the size. I had the same problem in a maze program that I wrote. I consider the dimensions to be in "nodes" instead of block but you could probably make the values <width> and <height> equal to half the value of tonumber(tArgs[1]) and [2] if it really bothers you.

Ugh, thinking about this, it would probably be somewhat complicated to keep to integers. Something like width = math.floor(0.5 * tonumber(tArgs[1]) should work. You want to do math.floor to round down so it fits within the parameters asked for. This should give something like a 6 x 6 "node" maze if you give it a <width> and <height> of 13. I hope that syntax works, I'll try it out later.
