Scripting

Introduction

There is a very, very basic internal scripting language that can be used through triggers, etc. You can also run scripts directly from from the game prompt using @pgm in the following manner:

@pgm <script>

At the moment, there is no protection at all as to what can be modified and by whom, besides the limitations of the script functions and the direct interpretation afforded by '@pgm' being restricted to admin or higher permissions.

Basics

The language syntax, structure, etc is based on Fuzzball MPI (http://www.fuzzball.org/docs/mpihelp.html). Every function returns a String, but there are essentially three cases: an empty string (""), a string representation of a value ("5"), and a string token (":true"). These loosely equate to void, int/number, and boolean return types.
