Array element
DEF INT ARRAY1[4,5]
Direct programming
DEFINE DIM1 AS 4
DEFINE DIM2 AS 5
DEF INT ARRAY[DIM1,DIM2]
ARRAY[DIM1-1,DIM2-1]=5
Indirect programming:
Field sizes must always be specified as fixed
values in array dimensions.
Axis instruction with axis variables
X1=100 X2=200
Direct programming
DEF AXIS AXVAR1 AXVAR2
AXVAR1=(X1) AXVAR2=(X2)
AX[AXVAR1]=100 AX[AXVAR2]=200
Indirect programming:
Define variables
Assign axis names Traverse axes stored in
the variables to 100 and 200.
Interpolation parameters with axis variables
G2 X100 I20
Direct programming
DEF AXIS AXVAR1=X
G2 X100 IP[AXVAR1]=20
Indirect programming:
Define and assign axis name
Indirect programming of center point
Indirect subprogram call
CALL "L" << R10
Call the program with the number contained
in R10
Additional notes
R parameters can also be interpreted as single-
dimensional arrays with abbreviated notation (R10
corresponds to R[10]).
