Variables (VARA)

There are several Variable object types. Variable objects can be static or dynamic. Static variables store values in their object definition, while dynamic variables retrieve values from a specified data source. Depending on a variable's content, you can use it to influence the processes of your Automation Engine system.

Static and Dynamic Variable Objects

There are several variable object types, they are grouped into static or dynamic categories as shown below.

Variable Type Variable Category Variable Category Description

Static Variable objects have values stored in their object definition.

You set static variable objects' values:

  • By manually entering them.
  • Note: Case-sensitive keys are supported. Example: Add the keys "test" and "TEST". If the database is case sensitive, it will save both keys, otherwise, the second entry will replace the first one.

  • Using the Cell Editor window. You open the Cell Editor window by clicking the icon for a cell. When cell text is on multiple lines, you must edit it in the Cell Editor window.
  • By defining a SET VARIABLE or CLEAR VARIABLE condition action for a Workflow task. However, you cannot define a new VARA object with a condition action.

The following script elements are available for STATIC and XML variables:

  • :PUT_VAR - Stores values in static variables.
  • :PUT_VAR_COL - Stores a value in a specific column of a static Variable object.
  • :DELETE_VAR - Deletes one or all values of a static variable.

The values of dynamic Variable objects are not stored in the object. They are directly retrieved from the specified data source while they are accessed. This process is referred to as variable resolution. Values can neither be defined by a user nor by script.


Reading Variable Object Values with the GET_VAR Script Function

The values of static and dynamic Variable objects can be read using the script function GET_VAR.

About the Many Kinds of Variables in Automation Engine

There are many kinds of variables in Automation Engine. There are the Variable object types and categories described above. Additionally, there are several additional kinds and groups of variables described below.

Automation Variables

A predefined subset of static VARA objects used for system properties. You can pick most of these variables in the Insert Variables dialog.dialog by selecting Automation Variables.

System Properties Variables

System properties variables are not objects. They are the same throughout the system. For example, &$SYSTEM# for the name of the Automation Engine system. You can pick most of these variables in the Insert Variables dialog.dialog by selecting System Properties. For a complete list, see System Properties.

Several System Properties variables are described in the topic Settings in Variables.

Object Properties Variables

Object properties variables reference objects or their runtime instance (task). They are either:

Script Variables (Including PromptSet Variables)

Script Variable are not objects. You set them in Automation Engine scripting to store values. Script variables can include numbers, strings, and date and time formats. You set script variables' values:

Script variables are used in scripts like &INPUT# and in the PromptSet designer like TEXTFIELD1#. Note that the leading & is not used, but if the variable is used in scripting, it requires it like &TEXTFIELD1#.

Object Variables

Object Variables store values that can be used throughout an object. They are defined on the Variables page of an executable object or with the :PSET script statement.

Agent Variables

Agent Variables are either available as Variable objects in the system client 0000 or directly stored in the database. If they are stored in the database, they are referred to as virtual agent variables. They can be read with the script element GET_VAR, but they cannot be set with the statement :PUT_VAR.

Predefined Variables

Predefined variables is an umbrella term that refers to all:
