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

GOTOF GoForward
instruction
- A GoTo operation is performed
to a block marked by a label;
the jump destination is in the
direction of the end of the
program.

IC Coordinate specified
using incremental
dimensions
- The dimension can be specified
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 GoTo operation to the block
with the following
label is
performed;
, otherwise, the next
instruction/block will follow.In
one block,
several IF instructions are
possible.
Relational operators:
= = equal, <> not equal
