Engraving with Okuma LR15

Hello, I have a question, I have a couple of Okuma LR15 machines with live tooling, one of them has y-axis. Does someone know how to programm engraving? I programm everything in G-code, without any CAM software, just using brackets to write the programm.

hy :) if you search a bit on forums, you could find macros for 1234567890, most likely fanuc

if so, could you convert them to okuma ? please feel free to ask anything / kindly :)
