Notecard reading

Here is a notecard reading template I use as a starting point.

key gSetupQueryId;
integer gSetupNotecardLine;
string  gSetupNotecardName = "setup";

//define config variables here
string gPassword;


readSettingsNotecard()
{
   gSetupNotecardLine = 0;
   gSetupQueryId = llGetNotecardLine(gSetupNotecardName, gSetupNotecardLine); 
}


default
{
    state_entry()
    {
         readSettingsNotecard();
    }
    dataserver(key queryId, string data)
    {
        if(queryId == gSetupQueryId) 
        {
            if(data != EOF)
            {
                list tmp = llParseString2List(data, ["="], []);
                string setting = llList2String(tmp, 0);
                
                if (setting == "password")
                {
                    gPassword=llList2String(tmp, 1);
                }
                //add more if statements here, for each config variable
                //you can also do stuff like variable=val1,val2,val3, simply
                //do llCSV2List(llList2String(tmp, 1));
                    
                gSetupQueryId = llGetNotecardLine(gSetupNotecardName, ++gSetupNotecardLine); 
            }
            else
            {
                state running;   
            }
        }
    }           
    changed(integer change)
    {
        if (change & CHANGED_INVENTORY)
            llResetScript();
    }
}

state running
{

    changed(integer change)
    {
        if (change & CHANGED_INVENTORY)
            llResetScript();
    }
}
