Engraving in the YZ plane G804
The cycles start engraving from the starting position or from the
current position, if no starting position is defined.
Example: If a character string is engraved with several calls, define the
starting position in the first call. All other calls are programmed without
a starting position.
G804 engraves character strings aligned linearly in the YZ plane.
Character set: see page 376
