Notepad++ took more like a whole second to paste everything (over 1,000,000 characters after all).  

Notepad++ is kind of the exception. It's a very lightweight program  . Bulky IDEs like the script editor in the student software tend to crash (or come very close) when I paste in the code, though. I don't even think the syntax highlighting can be turned off in the student software to avoid this issue.  
That's why I had to use the old scripting tools and Notepad++.

I clarified this in my previous post.

oh well, never mind then, my pc is probably faster than yours  

Once again, another great Nspire project!  Good work!

Figures. The student software must allow for more memory to be used. One thing that could be done is generate the table before hand. It would be faster and there wouldn't be two lists of words. 100,000 words is a bit excessive, so a dictionary with less words would also work. I tried actually sending this to my nspire cx, so as long as the rest of the program isn't massive, this should work. There are 81536 words. I'll attach the file of the pre-generated table.

Edits:

It takes a little more than 20 seconds for my calculator to open the document with the script. Indexing the table, however, takes less than a millisecond.

Also, don't forget to assign this table to a variable.

I wouldn't say "shrunken." This dictionary is probably larger than an array with the words. It just indexes a lot faster than an array since most of the guess and check is avoided.

When I load the script with the pre-generated table, Lua is using ~20 MB of the 64 MB of operating memory. TI probably set the max level lower than full capacity. So, maybe the table by itself is just small enough to fit in under their max but when the rest of the program is running, Lua uses even more memory and that signals to Lua to throw an error.

I can attach the program I used to generate the table and you can experiment with shorter tables.

I was looking at the 12dicts wordlists. Here's a download link: http://downloads.sourceforge.net/wordlist/alt12dicts-4.zip.
They come with some symbols to catagorize some of them, but I just deleted them all. I just used the replace feature in Notepad++ and turned on regular expressions. I had it find

[^a-z]

and replace it with nothing.

I also had it replace

\r\n

with

","

and added the brackets to make it a table.

Then, I assigned the result to the variable "list" in the attached program and ran it using Lua (on the computer). It will write to (or overwrite) a file called pregendict.txt (in the current directory) with the code for the pre-generated table.

Progress Report! 

(somewhat effective) Random Board Generation, Large 170,000+ words dictionary, A scrolling results page have all been added. Idk why I capitalized those random letters.

Screenshot included.

Edit: Anybody want a release yet?

Edit2: If anybody's wondering why that game ended at 1:30, I just changed the timer value so it wouldn't take as long to get to the results page.

Edit3: I got this little flashing icon  in the top right corner. It's the low memory icon! The same one from that one screenshot from OS 3.2 demonstrating the physics engine!

Currently, the Nspire seires doesn't support any kind of wireless or internet connectivity, not even with Ndless.

I'm glad you found a solution. It looks like there's less lag than I expected. A table probably takes up more memory than a string.
