deleting some values from a zl queue?

Hi, my name is Julieta,
I haven’t used Max for too long, and I am trying to work on the logic of my program. I am a little stuck on this, and I am wondering if someone would have any suggestions…. I have five spots on the floor (numbered 0 to 4) that are read as with a status ON of Off according to the presence of a person on that spot.
I need to keep track of the spots that are ON, and also the order in which they were activated. So I want to use a zl queue to store the spots that are turning ON, and then pop them in the same order after certain events. But if a spot is turned to OFF, I want to be able to remove it from the queue. Is this possible with a zl queue?

For example, if the spots 1, 4, 0 and 3 are turned ON, I store them in this order, the queue would pop 1, then 4, but if at that point I receive a signal that spot 0 is now OFF, I need to be able to remove the 0 from the queue so that the next one popped would be 3. etc.

I was using FUNBUFF before, which worked fantastic to track which ones were on or off, but I wasn’t able to keep track of the order.

Thanks in advance for any advice on this!

Julieta

hello – i would probably do this using lobjects http://arts.ucsc.edu/ems/Music/research/Lobjects.readme.html
it has objects for this and a bunch of other useful list operations. the attached patch does what you describe using lbuild, but there are many other ways..
