List of list names

I have script that keeps track of several functions using four list. The script performs similar function on all the lists. What I would like to know is if it is possible to use a list of list names to set up one user defined function to handle all of them. Something along the line of

llSearch(list which,string name,integer amount)
{
if(llListFindList(which,[name]) == -1)
{
which = which + name + amount;
}

where "which" could be list_1, list_2, list_3, or list_4

What you are describing isnt a list of lists, you are just passing a copy of the specific list in as a parameter called which. You will need to store the result back into the original list since LSL passes by value not by reference (hence the parameter being a copy). If your lists are large you may run in to stack problems.

list SearchAndAdd(list which, string name, integer amount)
{
    if(llListFindList(which,[name]) == -1)
    {
         which = (which = []) + which + [ name , amount ];
    }
    return which;
} 

And used as

MyList = SearchAndAdd(MyList, "Newgate Ludd",10);

Thanks
