Populating an Array

There are several ways to populate an array. The example code following each of these methods creates the exact same array, with the same elements:

• Use CreateArray when you initially create the array:

  Local Array of Number &MyArray;
  
  &MyArray = CreateArray(100, 200, 300);

• Assign values to the elements of the array:

  Local Array of Any &MYARRAY;
  
  &MYARRAY = CreateArray();
  &MYARRAY[1] = 100;
  &MYARRAY[2] = 200;
  &MYARRAY[3] = 300;

  Note: Using CreateArray without any parameters creates an array of Any.

• Use the Push method to add items to the end of the array:

  Local Array of Number &MYARRAY;
  Local Number &MYNUM;
  
  &MYARRAY = CreateArrayRept(&MYNUM, 0);
  /* this creates an empty array of number */
  &MYARRAY.Push(100);
  &MYARRAY.Push(200);
  &MYARRAY.Push(300);

• Use the Unshift method to add items to the beginning of the array:

  Local Array of Number &MYARRAY;
  Local Number &MYNUM;
  
  &MYARRAY = CreateArrayRept(&MYNUM, 0);
  /* this creates an empty array of number */
  &MYARRAY.Unshift(300);
  &MYARRAY.Unshift(200);
  &MYARRAY.Unshift(100);

You can also use CreateArrayRept (repeat) when you initially create the array. The following example creates an array with three elements: all three elements have the same data, that is, 100:

Local Array of Number &MYARRAY;

&MYARRAY = CreateArrayRept(100, 3);
