has released DAWG v1.0 for the TI-83 Plus and TI-83 Plus Silver Edition.
DAWG (Dictionary And Word Games) is a spell checker and also a word puzzle solver, anagram finder, and more. It is fast (most spell checks take less than a second). However, at 100kb, it is a bit large, due to its vocabulary of about 40,000 words.
