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

In addition to the 4 basic
arithmetic functions using the
operands + - * /, there are the
following arithmetic functions:
Degrees
Degrees
Degrees
The angle of the sum vector is
calculated from 2 vectors
standing vertically one on
another. The 2nd vector speci-
fied is always used for angle
reference.
Result in the range: -180 to
+180 degrees
Used instead of M2 - to main-
tain the continuous-path con-
