ARRAY INTEGER

ARRAY INTEGER ( arrayName ; size {; size2} )

Parameter	Type		Description
arrayName	Array	→	Name of the array
size	Integer	→	Number of elements in the array or Number of rows if size2 is specified
size2	Integer	→	Number of columns in a two-dimensional array

Description

The ARRAY INTEGER command creates and/or resizes an array of 2-byte Integer elements in memory.parameter is the name of the array.

• The size parameter is the number of elements in the array.
• The size2 parameter is optional; if size2 is specified, the command creates a two-dimensional array. In this case, size 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 as both an element and an array. This means that while working with the first dimension of the array, you can use other array commands to insert and delete entire arrays in a two-dimensional array.

While applying ARRAY INTEGER to an existing array:

• If you enlarge the array size, the existing elements are left unchanged, and the new elements are initialized to 0.
• If you reduce the array size, the last elements deleted from the array are lost.

Example 1

This example creates a process array of 100 2-byte Integer elements:

 ARRAY INTEGER(aiValues;100)

Example 2

This example creates a local array of 100 rows of 50 2-byte Integer elements:

 ARRAY INTEGER($aiValues;100;50)

Example 3

This example creates an interprocess array of 50 2-byte Integer elements, and sets each element to its element number:

 ARRAY INTEGER(◊aiValues;50)
 For($vlElem;1;50)
    ◊aiValues{$vlElem}:=$vlElem
 End for
