Num1D[1] refers to the 1st element
Num2D[1] refers to the 1st row
Num2D[1][1] refers to the 1st element of the 1st row
Num3D[1] refers to the 1st table
Num3D[1][1] refers to the 1st row of the 1st table
Num3D[1][1][1] refers to the 1st element of the 1st row of the 1st table
The following operations are legal:
Num2D[2] = Num1D
Num2D[5][5] = Num1D[5]
Num3D[2] = Num2D
Num3D[2][1] = Num1D
Num3D[2][1][1] = Num1D[1]
LENGTH_ARRAY and MAX_LENGTH_ARRAY are used to determine the effective and maximum lengths
of multidimensional arrays as shown in the following examples:
INTEGER Len
INTEGER My3DArray[5][3][4]
Len = MAX_LENGTH_ARRAY(My3Darray) // Len = 5
Len = MAX_LENGTH_ARRAY(My3Darray[1]) // Len = 3
Len = MAX_LENGTH_ARRAY(My3Darray[1][1]) // Len = 4
INTEGER Len
INTEGER My3DArray[5][3][4] =
{
{
{1,2,3,4},
{5,6,7,8},
{9,10,11}
},
{
{13,14}
}
}
Len = LENGTH_ARRAY(My3Darray) (* Len = 2, number of tables *)
Len = LENGTH_ARRAY(My3Darray[2]) (* Len = 1, number of rows in table 2 *)
Len = LENGTH_ARRAY(My3Darray[1][3]) (* Len = 3, number of columns in table
1, row 3 *)
