name     Array          Name of the array to create
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 Picture, 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.


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 PICTURE (◊Mine;0)

The following formula shows how to calculate the amount of memory used by a picture array:

    4+(1+number of elements)*4+sum of the size of each picture

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 Picture array is first created, its elements are empty.

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.
