Actually, this is what I do:

   if sDictFile[L] = true then...

which I thought would be pretty fast since it's accessing the array directly. The array looks 
like this:

   word1 -> true
   word2 -> true
   word3 -> true

And my loop does this, for each user word:

   if sDictFile["word2"] = true then...

so I'm not really looping through the keys, just looking for a matching one. The loop is for 
each user word I need to find. If there's no key, then the word isn't legal. I hope that makes
