How can I move an item of a list one place up or down

[FreezingFire]

You can have a look at an example that Garrett made at:

Here's the steps:

LIST SEEK to the item you want moved...
Copy @item(ListName) to a var...
LIST DELETE...
LIST SEEK to the position you want it inserted...
LIST INSERT, ListName, %%var

Remember that when you delete an item, the item index numbers
change from that point to the end of the list. So make sure you have
the correct index number to insert the item.

Cool Mac, I didn't know it's possible to use the LIST INSERT command like that, this is very useful.

It's a small error in the VDS documentation, making it seem you could only insert empty items:

"LIST INSERT,<list>"

All this info is in the example that was linked to above. It shows you how to move list items up and down, remove and add.

Tommy, I actually had no idea that the VDS help
file had omitted that. I must have just assumed
that LIST INSERT would follow the common usage
of the other LIST commands. Now I'm really glad
I posted it though.

BTW Garrett, I wasn't trying to steal your thunder...
But how many long time VDS users (like Tommy) would
have downloaded your example? I know I didn't.

Cheers, Mac

No, not thunder, just didn't want you to dissuade someone from actually downloading the example. It's an oldy moldy example and probably poorly written, but it does show the basics of manipulating the lists.

Garrett, my intention wasn't to dissuade anyone from
dloading your example. I just hate to dload stuff myself
if I can avoid it, and I figured if anyone needed further
instructions they'd get your example anyway. No harm
intended whatsoever.
