Siemens 840D Controller on a Finnpower punch - needing post

Greeting, I hate to be so needy, but this Siemens controller wants code significantly different from the posts I have laying around. It has these "DEF REAL" statements in the startup, and tool changes have a look ahead "TOOL(13,4.312,7.062)" calling tool number, x, and y locations. I've never had to do more then tweak a post. If anyone has something that might be a good starting place, I would sure appreciate it. Thanks ian
