size1 Number Number of elements in the array or number of
rows if size2 is specified
size2 Number Number of columns in a two dimensional array
Creates name, an array of type Integer, with size1 number of elements. If specified, name will be a two-dimensional array with size1 columns and size2 rows. If name already exists, the array is resized and elements that are not cropped retain their value.
The size2 parameter is optional; if it is specified the commands create two-dimensional arrays. In this case, size1 specifies the number of rows and size2 specifies the number of columns in each array.
Each row in a two-dimensional array can be treated like an element.This means that you can insert and delete entire arrays in a two-dimensional array with the other array commands.
Creates Name, an array of type Pointer, with Size1 number of elements specified, Name will be a two-dimensional array with Size1 columns and Size2 rows. If Name already exists, the array is resized and elements that are not cropped retain their value.
An element 0 (array name{0}) is always created for an array, and is set to a null value of the array type. Use the Size of array command to find the size of the array. the following line would delete all elements (except the 0 element), but leave the array defined:
ARRAY POINTER (◊Mine;0)
The following formula shows how to calculate the amount of memory used by a pointer array:
(1+number of elements)*16
Note: a few more bytes may be required to keep track of the selected element, the number of elements, and the array itself.
When a Pointer array is first created, its elements are empty values, that is NIL.
You refer to the elements by using curly braces. For example, MyArray{2} refers to the second element in the array MyArray. For two-dimensional arrays you refer to individual elements by using two sets of curly braces. For example, MyArray{3}{5} refers to the third row and fifth column.
