otherwise, change directly using
the T command

0 ... 9999 9999 Can be used to identify blocks
only integer, no with a number;
sign is written in the beginning of a
block
0 ... 9999 9999 Special block identification,
only integer, no used instead of N... ; such a
sign block should contain all
instructions for a complete
subsequent machining step.
1 ... 9999 Is used if the subroutine is run
only integer, no several times and is contained
sign in the same block as the call
