Implementing this trick speeds up the "sort" routine much (I think that the

You can find that accelerated handler as the "sort" handler of the "Text

Emmanuel,
There isn't any 'sort' handler in "Text Window" there (although 'Compare'
looks rather familiar), but there is one in the "Application" script of the
1.8.4-->1.8.7 upgrader that looks as if it must be the one. It contains :
-- credits to SBE & FD
<snip>
script listHolder
property theList : {}
property lowList : {}
property highList : {}
end script
set listHolder's theList to theList
<snip>
Yes?
