Learn to read program cnc lathe machine

If you look at the structure of a program cnc, What comes to your mind? Can you know how to read the program. Here I will explain my little knowledge about the structure of the program cnc.  

examples:
O0001
N005 G97 S250 M03
N010 T0101
N015 G00 X2.875 Z.1 M08
N020 G01 Z-2.0 F.008
N025 X3.1
N030 G00 X8.0 Z3.0 M09
N035 M30

The program can we describe as follows:
  1. O0001 All Fanuc programs begin
  2. N005  N words are sequence numbers for command identification
  • Turn Spindle On
  1. G97 Turn Spindle On Select RPM mode
  2. S250 Select speed
  3. M03 Turn spindle on in forward direction
  • Index Turret
  1. N010 T0101 Turret index command selects tool station and offset
  • Move Into Position

  2. X2.875 Approach X position

  4. M08 Turn on coolant
  • Feed Along Diameter
  1. N020 G01 Select cutting mode
  2. Z-2.0Z end point
  3. F.008 Cutting feedrate
