no llListSetElement?

Drat. I want to cache multiple notecards (say, half dozen of up to 10 lines each) upon script startup.

Bearing in mind that dataserver events can return results out of order, I am wondering what the best approach would be for building a list of strings (each element represents the contents of a notecard).

I understand the use of requestid's. I'm just pining for something like:

llListSetElement(list, elemNum, data)

(elemNum, in this case, would correspond to which notecard I am getting data from)

I suppose I am asking for a sparse array.

(the application is a picture frame, where each photo has a few lines of description in a notecard that is named similiarly)

Make sure the lists starts with empty elements.. e.g.

list myvar = [ "", "", "", ""];

and use llListReplaceList.

I made a funciton that does something similar for strided lists. The rest of the strided functions are Here.

// Replace a Stride in a List
list fncReplaceStride(list lstSource, list lstStride, integer intIndex, integer intStride)
{
  integer intNumStrides = fncStrideCount(lstSource, intStride);
  
  if (llGetListLength(lstStride) != intStride) { return ["-1"]; }
  
  if (intNumStrides != 0 && intIndex < intNumStrides)
  {
    integer intOffset = intIndex * intStride;
    return llListReplaceList(lstSource, lstStride, intOffset, intOffset + (intStride - 1));
  }
  return ["-1"];
}

// Update a single item in a Stride within a List
list fncUpdateStride(list lstSource, list lstItem, integer intIndex, integer intSubIndex, integer intStride)
{
  integer intNumStrides = fncStrideCount(lstSource, intStride);
  
  if (llGetListLength(lstItem) != 1) { return ["-1"]; }
  
  if (intNumStrides != 0 && intIndex < intNumStrides)
  {
    integer intOffset = (intIndex * intStride) + intSubIndex;
    return llListReplaceList(lstSource, lstItem, intOffset, intOffset);
  }
  return ["-1"];
}

I'm sure you can compare those two and figgure out what i'm doing.
