Populating Array in Poeplecode

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);


----------------------------------------------------------------------

Using CreateArray without any parameters creates an array of Any.

Local Array of Any &MYARRAY;

 &MYARRAY = CreateArray();
 &MYARRAY[1] = 100;
 &MYARRAY[2] = 200;
 &MYARRAY[3] = 300;

------------------------------------------------------------------------


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);
