	Using Node Items to Employ Variables

Many nodes have palette options in which you can make use of variables in your Dialog Designer speech projects. To offer a few examples, you can:

Use an Operation palette option in the Data node to assign values to variables or to perform calculations or other manipulations on variable values.

Use a database operation to retrieve a telephone number from a database, and then assign that number to a variable. You can then use that variable as the transfer destination variable in a call transfer.

Include application performance and call information data in variables within a Report item. This data can be sent to an IVR system such as Avaya Voice Portal. There you can use it to prepare reports and analyze application data.

Other nodes have options in which you can make use of the system variables to set branching conditions, for instance. You can also use system variables pass variable values to other application modules.

In each case, the variable must exist before you can use it in a node item. If the variable does not already exist as a system variable or a Dialog Designer-generated variable, you must create a custom variable to do the job.

In all cases, palette options and items in which you can employ variables or variable fields are documented in the individual descriptions of those options and items. See Nodes and Palette Options.
