Specification

<lsl>//This version converts all list items into strings. list ListKeyCase(list src,integer case){

   list new;
   integer i;
   if (case){
       do
           new += llToUpper(llList2String(src,i));
       while (llGetListLength(src)>++i);
       return new;

}</lsl>

<lsl>//This version preserves the types of all list items. list ListKeyCase(list src, integer case) {

   list new;

Caveats

• Key equality (and inequality) testing is case sensitive.

Examples

<lsl> list test = ["Apples","Bananas","Cranberrys","Donuts"]; list newtest = ListKeyCase(test,0);

//newtest now is ["apples","bananas","cranberrys","donuts"]</lsl>
