Then I tried a slightly more complex way:
setup
 >   put url ("file:" & tFile) into gWords
   repeat for each word w in gWords
     put 1 into  gArray[w]
   end repeat
and then
   put tWords into field "inField"
   put 0 into t
   repeat for each word w in tWords
     add 1 to t
     replace "." with empty in w
     replace "," with empty in w
     replace "!" with empty in w
     if gArray[w] <> 1 then
       set the textstyle of word t of field "inField" to "bold"
     end if
 >   end repeat
This took 2 millisecs for 50 words, so would be reasonable for even
large-ish documents.
I tried to put this sample stack onto RevOnline - but I'm having some
problem connecting to the server, so you can find it instead at
   www.tweedly.net/RunRev/SpellCheck.rev
   www.tweedly.net/RunRev/allwords.dic
(remember the dic is 1.75M - don't download it unless you really want it !)

Alex,
Coming from FORTRAN, I have never really appreciated the more 
flexible use of arrays in Runtime Revolution. Your solution to the 
spell check problem is a Runtime revelation.

However a naive question: Since you  only use the gArray, would it be 
possible somehow to store the information in the gArray in a file (I 
don't mean store all the 1's), and use that directly in the repeat 
loop, rather than store the dictionary gWords in a file and then have 
to construct the gArray?
