Ain't that the truth.

I fixed this to use lists... Maybe.
put parentArray( LISTNEW ) into aNew
put parentArray( LISTOLD ) into aOld
intersect aNew with aOld -- Remove from aOld that which is not in aNew
union aOld with aNew recursively -- Leaves aNew unchanged except that children
in aOld are brought in. I think.

I know this does not attend to the question, but my feelings are like this: if
one has control, go back and use arrays from the start.
Now, to your comments on robustness in parsing the files. I suppose any
whitespace at the start of a line could be considered a child. Also, it is an
error if
Hmmm. I had mentioned earlier:
"You cannot just find matching lines between the two lists, because some
children
AND some parents may be present in both...
The discussion has focused on array lore, and that is fine, but are we all
in agreement that the main task is to isolate the parents, regar
My mistake. I was thinking arrays.

Yikes! I wasn't aware of duplicate keys being a problem. How does that happen?

I'm a great fan of, and user of, arrays - but we always need to be
careful of losing data with duplicated keys.
You haven't said that the parent names in LISTNEW are guaranteed to be
unique. This simple code assumes they are - if they're not, it's easy to
add a check ... (And it also assumes

I'm pretty sure I goofed somewhere, but maybe something like this?

I agree that the lack of formatting makes it hard to communicate. I would favor
changing the list settings to allow for it. I don't think we have a spam
problem that would discourage that.
And to help support this, LC copy should include types easily pasted into mail
clients.

I saw your post preceded my second one.
Besides the fact that this works as well and is faster:
repeat for each line tLine in tAll
put tLine into myArray[ tLine]
end repeat
The array thing is the easy part. The real working of this gadget depends on
being able to isolate the children
I'd tend to look for ways to do this with functions that work on whole
collections and avoid loops.
If that is not found, or is hard to work with, I'd change the lists to be
arrays.
Each array is is keyed by parents. Each parent is an array of children.
Children can be represented as an array
I really do not like the use-list. It is difficult to format one's answers.
Here is a handler that places a few pieces of data into two variables. These
would be the two isolated lists of children derived from the parents as
described earlier. There is one difference between the two lists, the chi
