A position (rotary around X)
B position (rotary around Y)
C position (rotary around Z)
U Relative axis parallel to X
V Relative axis parallel to Y
W Relative axis parallel to Z
M code (another "action" register or Machine code(*)) (otherwise referred to as a "Miscellaneous" function")
F feed rate
S spindle speed
