102
(7) Prompt character display (G280)
The prompt character is the character to prompt input. This can be
displayed to the character row input mode (when input control
variable #8502=3). The specification method for the character row
is the same as for G243.

G280 Pp ;
Note
G280 is a one–shot G code. Namely, it is enabled only for
the commanded block.
(8) Dot coordinate system setting (G392)
Sets the dot coordinate system by graphic coordinate system.
Subsequent commanded drawing commands will be commands in
this coordinate system.

(9) Absolute command (G390), incremental command (G391)
Commands whether coordinate commands in character coordinate
system, graphic coordinate system are absolute mode commands
(G390) or incremental mode commands (G391).
(10)Linear drawing (G301)
Draws lines in specified X, Y coordinates.
