- A GoTo operation is performed
to a block marked by a label;
the jump destination is in the
direction of the program start.
- 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.
- The dimension can be specified
for the end or center point of a
certain axis irrespective of G90.
- If the jump condition is fulfilled,
the GoTo operation to the block
with the following
performed;
instruction/block will follow.In
one block,
several IF instructions are
possible.
