Barry The Hatchet posted a good roll up of the script naming conventions the CODI project came up with in NWN1. Here's the link: http://nwcitadel.forgottenrealmsweave.org/showthread.php?t=1131
Here's the actual list:
Include Scripts
Include scripts should be prefixed with INC_
Event Driven Scripts
Following the prefix for EVENT driven scripts, this is the majority; you have 1 letter denoting the object type that has the event this script goes in, they are as follows:
* N - NPC
* M - Monster/Creature
* A - Area
* O - Module
* P - Placable
* T - Trigger
* D - Door
* R - Trap
* C - Conversation
* E - Encounter
* I - Item - This script is not placed on an item per se, but called by module level scripts.
* X - No Object - Use this for a script that is called by other scripts. Executable scripts.
