That would work.

The application would be one of gatering all the lines in a text field that
contain a word or words and displaying them in a second field. The text might
also include quotes and that messes up the wordOffset function.
Turns out the tokens don't work since the period is not a token so the token 1
of "time." is time.
Astonishingly, it turns out that LC all allows for
Put "time" is among the tokens of "Now is the time, for all good men."
That returns true.
But
Put "men" is among the tokens of "Now is the time, for all good men."
returns false--because of the period after "men"
I think I'll just strip the lead and trailing characters from the resulting
wordOffset word, using something like:
function stripEnds tWord
repeat
if charIsNotLetter (char 1 of tWord) then
delete char 1 of tWord
next repeat
else
exit repeat
end if
end repeat
repeat
if charIsNotLetter (char -1 of tWord) then
delete char -1 of tWord
next repeat
else
exit repeat
end if
end repeat
return tWord
end stripEnds
function charIsNotLetter tChar
put charToNum(tChar) into tNum
switch
case tNum >= charToNum("a") and tNum <= charToNum("z")
return false
break
case tNum >= charToNum("A") and tNum <= charToNum("Z")
return false
break
default
return true
end switch
end charIsNotLetter
But I would prefer RR to implement your suggestion of augmenting the
delimiters for "word" to include all non-letters.
