Create Empty 2D Array

Activity allows to create an empty two-dimensional array.
Arrays are used to store multiple elements as a single variable. An array is the data structure that stores a fixed number of elements of the same data type. The type of data stored in the array has to be specified beforehand. You cannot change the size or type of an existing array after it has been created. The elements of an array are indexed, starting with index (0)(0) - the first rank denotes the number of row, and the second one defines number of column.

The following figure illustrates the two-dimensional array 3x4 divided into rows and columns.

Dragging the activity to flowchart opens an input window requiring you to select your array’s data type, followed by activity window itself. You can specify the size of the array (give the number of rows and columns) and give a name to the Array there (create a variable, type e.g. String[][] or Int32[][], it must match chosen Element Type).

Array elements can be accessed using an index - simply type array name followed by element's indices in brackets (arr2d(1)(2) addreses to the element of the array "hh" - illustration above).

Parameter Name	Parameter Type	In/Out	Description
Alternative Scenario If Failed	Boolean	Input	checkbox; default is "on"
Array	Literal	Output	name of the array
Columns	Int32	Input	number of columns of the array
Display Name	Literal	Input	changes display name of the activity
Element Type	Dropdown	Input	select element type from the dropdown list
Exclude from Transaction Check	Boolean	Input	checkbox; default is "off"
Result	Boolean	Output	returns a Boolean value. True if no error in activity, otherwise will return False
Result Code	Int32	Output	Result Code will return 0 if there is no error in activity, otherwise in most cases it will return 1, the extended result code will show only in several chosen activities
Rows	Int32	Input	number of rows of the array
