[solved].bot file problem(circuit CAM).

I've get this bot file and my project is to read it and display all the welding plate. when i open it i found it rather readable. but soon a problem pops up.
the first several lines are like this:

lines at beginning are obviously defining some of the plates..D18 to D30. all the lines below that indicate the position and plate Number.
but i can't find any information about D03..or D02,D01 which appears later.
now the weird thing is if i import this file in circuit CAM. it looks normal.
so anyone know where can i get the information about D03?


ps. also.. any one know how does this coordinates work?
ie where is the origin? what is the unit?
thanks very much in advance.


[solved] thanks andre_teprom
that's pretty hardcore.

There is missing the apperture file with the mapping drills.
Take a look here, wich explains Gerber format sintax commands :

What's All This About RS274X Anyway?
