Va lue assignments In formation
- A GoTo operation is per-
formed to a block marked by a
label; the jump destination is
in the direction of the program
start.
- 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.
The dimension can be speci-
fied for the end or center point
of a certain axis irrespective of
G90.
- If the jump condition is fulfilled,
the jump to the block with
Label: is performed
wise, next instruction/block;
several IF instructions per
block are possible
