There isn't as much info on lists on the wiki as I'd like. I'm plugging along, but if anyone has any good examples of 'everything about lists'.

I'd appreciate being pointed in the proper direction. I think the hardest thing I'm having trouble with is removing items from a list right now.

I don't believe it's so much the WIKI lacking on explaining lists, but rather that lists aren't as versatile as people first expect (many expect array-like functionality).

To delete something from a list, use llDeleteSubList().

Example:

lsample = llDeleteSubList(lsample, 0, 1);

The above example would remove the 1st and 2nd entry from list lsample.

If you don't know the position of a particular variable that you want to delete, run something like:

x = llListFindList(lsample, [data]);
if(x != -1) lsample = llDeleteSubList(lsample,x,x);

The scary part is that eventually one gets used to such indignities as the equivalent of an array operation such as:

arrayVar++;

being something like:

listVar = llListReplaceList(listVar, [llList2Integer(listVar, i) + 1], i, i);

(and then hunting around for why heap is fragmenting). :rolleyes:

oops. I had been trying to use a substring query, thinking that was better, based on some wording in one of the wikis. I'll go this path instead, it'll probably solve what I was having trouble with. As always, thanks for the input.
