0 ... 9999 9999 Can be used to identify blocks with
only integer, no a number; is written at the begin-
sign ning of a block.
0 ... 9999 9999 Special block identification, used
only integer, no instead of N... ; such a block
sign 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 in
sign the same block as the call
