1.1.6 List of instructions
The functions marked with an asterisk (*) are active at the start of the program in the CNC
turning version, unless otherwise programmed or the machine manufacturer has preserved
the default setting for the "turning" technology.

G G function
(preparatory
function)
Only integer, specified
values
The G functions are divided into
G groups. Only one G function
of a group can be programmed
in a block.
A G function can be either
modal (until it is canceled by
another function of the same
group) or only effective for the
block in which it is programmed
(non-modal).
