This description of the coordinate system, subroutine and variables is relevant for DDCSV3.1?

-----------------------------------------------
DDCSV Coordinate System Description:

The coordinate systems in DDCSV system include machine coordinate system, G53 coordinate system and G54-G59 coordinate system.

The machine coordinate system is established by home operation or zero under MACH. Read # 864- # 867 (X, Y, Z, A) to get the position in the machine coordinate system.

G53 is based on the machine coordinate system. # 800- # 803 (X, Y, Z, A) describes the distance from the origin of the G53 coordinate system to the origin of the machine coordinate system. Adjusting these parameters can reconstruct the G53 coordinate system. Read # 868- # 871 (X, Y, Z, A) to get the position in G53.

The G54-G59 coordinate system is based on the G53 coordinate system. # 804- # 807 (G54 X, Y, Z, A), # 808- # 811 (G55 X, Y, Z, A), # 812- # 815 (G56 X, Y, Z, A), # 816- # 819 (G57 X, Y, Z, A), # 820- # 823 (G58 X, Y, Z, A) , # 824- # 827 (G59 X, Y, Z, A) respectively describe the distance from the origin of G54-G59 coordinate system to the origin of G53 coordinate system, and you can adjust these parameters to reconstruct the G54-G59;

Read #840-#843(G54 X、Y、Z、A)、#844-#847(G55 X、Y、Z、A)、#848-#851(G56 X、Y、Z、A)、#852-#855(G57 X、Y、Z、A)、#856-#859(G58 X、Y、Z、A)、#860-#863(G59 X、Y、Z、A) to get the position in G54-G59.

#516 describes the system currently working coordinate system, 0 corresponds to the G53 coordinate system, 1-6 corresponds to the G54-G59 coordinate system, 7 corresponds to the machine coordinate system.

Reading #699-#702 can get the coordinates in the current workpiece coordinate system.
--------------------------------
The DDCSV system supports user-defined G code (G100-G199). The user can add the corresponding subroutine in slib.nc to customize the G code. The subroutine O9100-O9199 corresponds to G100-G199.

The following macro variables provide support for user-defined G code:

#451-#454 is the position of the workpiece coordinate system at the end of the current Gcode line

#448 is used to identify G20/G21 mode, #448=25.4 in G20 mode, #448=1 in G21 mode
#449 is used to identify G98/G99 mode, #449=1 in G99 mode, #449=-1 in G98 mode
#450 is used to identify G90/G91 mode, #450=1 in G90 (G90.1) mode, #450=-1 in G91 (G91.1) mode

#420 is used to identify whether there is X size word in the current Gcode line. If it exists, #420=1, otherwise #420=0
#421 is used to identify whether there is Y size word in the current Gcode line. If it exists, #421=1, otherwise #421=0
#422 is used to identify whether there is Z size word in the current Gcode line. If it exists, #422=1, otherwise #422=0
#423 is used to identify whether there is A size word in the current Gcode line. If it exists, #423=1, otherwise #423=0
#424 is used to identify whether there is B size word in the current Gcode line. If it exists, #424=1, otherwise #424=0
#425 is used to identify whether there is C size word in the current Gcode line. If it exists, #425=1, otherwise #425=0
#426 is used to identify whether there is I size word in the current Gcode line. If it exists, #426=1, otherwise #426=0
#427 is used to identify whether there is J size word in the current Gcode line. If it exists, #427=1, otherwise #427=0
#428 is used to identify whether there is K size word in the current Gcode line. If it exists, #428=1, otherwise #428=0
#429 is used to identify whether there is R size word in the current Gcode line. If it exists, #429=1, otherwise #429=0
#430 is used to identify whether there is L size word in the current Gcode line. If it exists, #430=1, otherwise #430=0
#431 is used to identify whether there is H size word in the current Gcode line. If it exists, #431=1, otherwise #431=0
#432 is used to identify whether there is P size word in the current Gcode line. If it exists, #432=1, otherwise #432=0
#433 is used to identify whether there is Q size word in the current Gcode line. If it exists, #433=1, otherwise #433=0

#484 is used to record the current Gcode line P size word
#485 is used to record the current Gcode line Q size word
