I'm trying to make a list that varies in size depending on how many numbers you're putting into it. Ideally I would have something like 5 sliders, and any slider with a value of 0 (or whatever) would be kept from the list. If all the sliders were at zero, the list would be empty/there would not be a list. If a slider value is higher than 0, then that value is put in the list.

I'm relatively new to this kind of data management kind of stuff, so I'm not sure if there's an obvious way to do this I've somehow missed. listfunnel says it can make variable length lists but it's not clear to me how.

I've been looking at zl, and I've been looking at jitter matrixes for maybe storing all the slider data and then looking up positions selectively. I'm working on that now and I'll post if I get something to work, but I was wondering if there is an every-day way to do this (or maybe matrixes etc ARE the every-day way). It seems like there could be something simple I'm missing.

make-a-dynamicvariable-list

for the given example i would just make a list of all numbers and then remove all 0s (all list elements which match 0.)

zl union or zl compare can do things like that.

or, let's be crazy here... [zl filter 0]?

or zl filter I suppose. I think I was making the issue harder than it had to be. I have to do some number crunching afterwards but that's no problem.

yeah... that's pretty obvious really I suppose.

I was hoping to preserve the zeros somehow and have it toggle the slider data on/off, but that's not really as elegant as this anyway. plus I can move on to other things.

Make a dynamic/variable list?
