Is there a way to sort by multiple columns? For example, how can I sort 1st by column 5 descending and 2nd by column 8 ascending and 3rd by column 11 ascending?

I do multiple column sorting by using TRO's binary system. His Next NTRI filter uses this, as an example.

Actually, in practice, this will never work. Here's why. Suppose you just finished sorting the first column in ascending order. So far, so good. Now you want to sort the second column in descending order. But what happens? The second column gets sorted as desired, but the first column is in disarray. Hmm, you scratch ure head and go back to sorting the first column again. But this time the second column comes out as all messed up. So you laboriously sort the second column again only to find the first column out of synch...yet again. (I'm sure you don't need me to explain why they don't line up.)
Repeat this five more times and you would rather put a bullet in ure head instead.

Should also point out that I combine TRO's binary sort(s) with an added analog sort(s). All the math works out into a single number that is in a single column and is sorted by SF. One has to have some math skills to do this.

Yes, lurking in the shadows :)
SF has more comical value to me these days....
If people would study the work that you've done on SF they would be much better off!

You got that right!
Why reinvent the wheel when the work's already been done for you.
LOL!
