Hi Ted

That helps so much as I see how it works now, except I was hoping for sorting in the other 'dimension' if I can use that turn of phrase.

I was thinking about a list of lists where each child list is an individual record, from a table of similar records.

[…]

I could run transpose the lists into {{"adam","penny",…}, {"male","female",…}, {33, 43,…}} I guess. But is there a way to do it if I have lists of records like this, or even as lists with property labels (hashes) {name: "adam, gender: "male", age: 33}, etc etc

transposing is the only way to go (unless you want to turn to ASObjC). you can do it like so:

———

set transposedList to transposeList(random_list_of_lists)

set sortedTransposedList to sortlist transposedList comparison 1 with respect to {2, 3, 1} with ascending and remove duplicates -- wrong interpretation!

set sorted_list_of_lists to transposeList(sortedTransposedList)

to transposeList(inList)

set outList to {}

repeat with thisSubList in inList

repeat with i from 1 to count of thisSubList

try

set end of item i of outList to item i of thisSubList

on error

set end of outList to {item i of thisSubList}

end try

end repeat

return outList

end transposeList

———

If you want to sort records you’ll need to get a custom sorting algorithm. Google “A Dose of Sorts” which gives an assortment of pure-applescript sorting routines. The full package is TMI, but I’ve used the generic quicksort routine to sort records before.
