In Need of 3 axis mill sample program

Good Afternoon,

I am in need of a 3 axis milling sample program. I am converting my Anilam Crusader M 3 axis mill to LinuxCNC. I use Gibbscam and in order to help me with the post processor they need a sample program that contains gcode that generate lines, circles, tool changes, etc. I sent them a link to the LinuxCNC G Code catalog. Any help is greatly appreciated.

Thank You,
Steve in Indy
