I need a result set that I can repeat through, thanks.

I'm missing something here; do you need help with a script, or do you simply want text to work on? If the latter, just copy something from a news article on a web site, or something like that.


If the former, try this:

set foo to sometext  --replace "sometext" with real text
if length of foo is greater than 256 then
	set bar to text 1 through 256 of foo
	repeat until the last character of bar is space
		set bar to text 1 through -2 of bar
	end repeat
	set bar to text 1 through -2 of bar
else
	set bar to foo
end if

The above script assumes that if the original text is 256 characters or less, it doesn't matter whether it ends with a word.

Alternatively, if you don't mind stripping punctuation in the middle of the text, try this:

if length of foo is greater than 256 then
	set bar to text 1 through 256 of foo
	if character 257 of foo is not space then
		set bar to words 1 through -2 of bar
		set text item delimiters to space
		set bar to bar as text
		set text item delimiters to ""
	end if
else
	set bar to foo
end if
bar
