Someone may have a more sofisticated answer but basically you need to understand the program you want to use. The program will have an expected place to start. It might be spelled out in the program comments or setup instructions. Most programs I write are set to start at x,y,z zero and that point might be in the middle of a hole in the part or a corner or such like.
Once you know where that point is, and what it's co-ordinates are you can move the machine manually to there and set the DRO displays to those values.
For my programs I spell it out in the comments at the top. I usually program the start point as 0,0,0 as I said then it's just a mater of placing the cutter there and zeroing the DRO's. If it's a hole or an edge you can use a center or edge finder manually then zero everything and off you go.
The toolpath display may give some sort of indication as well as to what it's going to do but if nothing else you'll need to be able to read the gcode and see what it's trying to do.
