1.1 Variables
Array index
The implicit sequence of the array elements, e.g. in the case of value assignment using SET
or REP, is right to left due to iteration of the array index.
Example: Initialization of a 3-dimensional array with 24 array elements:
DEF INT FELD[2,3,4] = REP(1,24)
FELD[0,0,0] = 1
FELD[0,0,1] = 1
FELD[0,0,2] = 1
FELD[0,0,3] = 1
...
FELD[0,1,0] = 1
FELD[0,1,1] = 1
...
FELD[0,2,3] = 1
FELD[1,0,0] = 1
FELD[1,0,1] = 1
...
FELD[1,2,3] = 1
corresponding to:
FOR n=0 TO 1
FOR m=0 TO 2
ENDFOR
ENDFOR
Example: Initializing complete variable arrays
For the actual assignment, refer to the diagram.
Program code
N10 DEF REAL FELD1[10,3]=SET(0,0,0,10,11,12,20,20,20,30,30,30,40,40,40,)
N20 ARRAY1[0,0] = REP(100)
N30 ARRAY1[5,0] = REP(-100)
N40 FELD1[0,0]=SET(0,1,2,-10,-11,-12,-20,-20,-20,-30, , , ,-40,-40,-50,-60,-70)
N50 FELD1[8,1]=SET(8.1,8.2,9.0,9.1,9.2)
