ARRAY STRING

version 3

ARRAY STRING (strLen; arrayName; size{; size2})

The ARRAY STRING command creates and/or resizes an array of String elements in memory.

• The strLen parameter specifies the maximum number of characters that can be contained in each array element in a string array. The length can be from 1 to 255 characters.

• The arrayName 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 STRING to an existing array:

• If you enlarge the array size, the existing elements are left unchanged, and the new elements are initialized to "" (empty string).

• If you reduce the array size, the last elements deleted from the array are lost.

1. This example creates a process array of 100 31-character String elements:

   ARRAY STRING (31;asValues;100)

2. This example creates a local array of 100 rows of 50 63-character String elements:

   ARRAY STRING (63;$asValues;100;50)

3. This example creates an interprocess array of 50 255-character String elements and sets each element to the value "Element #" followed by its element number:

   ARRAY STRING (255;<>asValues;50)
   For ($vlElem;1;50)
      <>asValues{$vlElem}:="Element #"+String($vlElem)
   End for

ARRAY TEXT.
