I need help

I’m new with OKUMA OSP 5020L and I have problem with
writing the program. I write the program on this way:

%
O0001
N0000 G13
N0001 G00 X0. Z0. S1200 T0505 G42 G03
N0002 GO2

But the machine doesn’t start working
In EDIT I see the whole program but in AUTO it doesn’t show the beginning.

Please help me
