GOTOB
GoBack instruction
-
A GoTo operation is per-
formed to a block marked by a
label; the jump destination is
in the direction of the program
start.

N100 GOTOB LABEL1
GOTOF
GoForward instruc-
tion
-
A GoTo operation is per-
formed to a block marked by a
label; the jump destination is
in the direction of the end of
the program.

N130 LABEL2: ...
IC
Coordinate specified
using incremental
dimensions
The dimension can be speci-
fied for the end or center point
of a certain axis irrespective of
G90.
N10 G90 X10 Z=IC(20); Z -
incremental dimension, X -
absolute dimension
IF
Jump condition
-
If the jump condition is fulfilled,
the jump to the block with
Label: is performed ; other-
wise, next instruction/block;
several IF instructions per
block are possible
Relational operators:
= = equal, <> not equal, >
greater than, < less than, >=
greater than or equal to, <=
less than or equal to
